Answer:

stainless steel

Explanation:

Flashing can be made from many different materials, including metal (copper, aluminum, stainless steel, lead, etc.)

The maximum speed with which the car can make the turn is 13.69 m/s (Option C)

We'll begin by obtaining the force. This can be obtained as follow:

F = μN

F = 0.75 × 15000

F = 11250 N

Finally, we shall determine the maximum speed. Details below:

F = mv²/r

11250 = (1500 × v²) / 25

Cross multiply

1500 × v² = 11250 × 25

Dive both sides by 1500

v² = (11250 × 25) / 1500

Take the square root of both sides

v = √[(11250 × 25) / 1500]

v = 13.69 m/s

Thus, the maximum speed is 13.69 m/s (Option C)

The final speed of both playdoughs which stick together after the collision is 0.5 m/s

The mass of the first playdough = 0.5 kg

The mass of the second playdough = 0.25 kg

The initial speed of the first playdough =  1.5 m/s

The initial speed of the second playdough = 2 m/s

The final speed of both playdoughs can be found using the formula,

       m₁u₁ + m₂u₂ = (m₁ + m₂) v

where m₁,m₂ is the mass of the first and second playdough respectively

           u₁,u₂ is the initial speed of the first and second playdough respectively

           v is the final speed of both playdough

Let us substitute the known values in the above equation, we get

          0.5 x 1.5 + 0.25 x 2 = (0.5 + 0.25) v

                         0.75 x 0.5 = 0.75v

                                  0.375 = 0.75v

                                         v = 0.375 / 0.75

The total distance described by the rubber ball before it comes to rest is 100 meters.

At the first drop, the ball falls from a height of 50 meters, and then rebounds to a height of 25 meters. So, the distance covered in the first drop and rebound is 50 + 25 = 75 meters.

At the second drop, the ball falls from a height of 25 meters and rebounds to a height of 12.5 meters. So, the distance covered in the second drop and rebound is 25 + 12.5 = 37.5 meters.

At the third drop, the ball falls from a height of 12.5 meters and rebounds to a height of 6.25 meters. So, the distance covered in the third drop and rebound is 12.5 + 6.25 = 18.75 meters.

This process repeats until the height of the rebound is less than 0.01 meters, at which point we consider the ball to have come to rest.

The total distance covered by the ball is the sum of all the distances covered during each drop and rebound, which is:

75 + 37.5 + 18.75 + 9.375 + 4.6875 + 2.34375 + ...

This is a geometric series with first term 75 and common ratio 1/2. Using the formula for the sum of an infinite geometric series, we get:

total distance = 75 / (1 - 1/2) = 100 meters.

Answer:

When two objects in motion hit each other they experience forces that are equal in magnitude and opposite in direction. This force causes one of the objects to speed up or gain momentum and other to slow down or lose momentum.

Initial speed of the coin (u)= 0 (As the coin is released from rest)

Acceleration due to gravity (a) = g = 9.81 m/s²

Time of fall (t) = 1.5 s

From equation of motion we have:

\( \boxed{ \bf{v = u + at}}\)

By substituting values in the equation, we get:

\( \longrightarrow \) v = 0 + 9.81 × 1.5

Answer:

Explanation:

In order to estimate the time at which the cars will be side by side, we would need to know the initial positions and velocities of the cars, as well as any external factors that may affect their motion, such as friction, air resistance, or changes in acceleration.

We would also need to know the length of the road, the direction in which the cars are traveling, and any other relevant details about the situation.

Once we have this information, we could use kinematic equations to calculate the time at which the cars will be side by side, based on their initial conditions and any changes in their motion.

However, without this information, any estimate would be purely speculative and likely to be inaccurate.

Answer:

C

Explanation:

The electric force between two charged particles decreases by a factor of 4 if the distance between them is increased by a factor of 2. This is because the electric force is inversely proportional to the square of the distance between the charges. So, if the distance is doubled, the force is 1/4 as strong.

Thus, The answer is C.

The main answer to the problem is:T = m(g + a)where T is the tension force, m is the mass of the object, g is the acceleration due to gravity (9.8 m/s2) and a is the upward acceleration of the object (1.50 m/s2).

The tension force in a rope or cable is the force that is transmitted through the rope when a force is applied at one end of the rope. In this problem, the gymnast is climbing up the rope with an upward acceleration of magnitude 1.50 m/s2. We can use the equation T = m(g + a) to calculate the tension force in the rope

.To use the equation, we need to know the mass of the gymnast. Let's assume that the mass of the gymnast is 60 kg. We also know that the acceleration due to gravity is 9.8 m/s2.Substituting the values into the equation:T = m(g + a)T = 60 kg (9.8 m/s2 + 1.50 m/s2)T = 60 kg (11.3 m/s2)T = 678 NTherefore, the tension force in the rope is 678 N.

The magnitude of the velocity of the 6.0 kg mass after the collision is approximately 1.7 m/s.

We can solve this problem using conservation of momentum and conservation of kinetic energy. Conservation of momentum states that the total momentum of a system is conserved if there are no external forces acting on it. In this case, the system is the two masses.

Let p1 and p2 be the initial momenta of the 3.0 kg and 6.0 kg masses, respectively, and p1' and p2' be their final momenta after the collision. Since the 6.0 kg mass is initially at rest, we have:

p1 = m1v1 = (3.0 kg)(10 m/s) = 30 kg·m/s

p2 = m2v2 = (6.0 kg)(0 m/s) = 0 kg·m/s

After the collision, the 3.0 kg mass moves at an angle of 35° with a speed of 8.0 m/s. We can break its velocity into x- and y-components:

vx = v1' cos(35°) = 8.0 m/s cos(35°) ≈ 6.6 m/s

vy = v1' sin(35°) = 8.0 m/s sin(35°) ≈ 4.6 m/s

The total momentum of the system after the collision is:

p1' + p2' = m1v1' + m2v2'

We can use conservation of momentum to say that p1 + p2 = p1' + p2', so:

p1' + p2' = 30 kg·m/s

Substituting in the known values, we have:

(3.0 kg)(6.6 m/s) + (6.0 kg)v2' = 30 kg·m/s

Solving for v2', we get:

v2' = (30 kg·m/s - 19.8 kg·m/s) / 6.0 kg ≈ 1.7 m/s

Impact of the car with the object. There are two collisions that happen during a crash, the first one is the impact of the car with the object and the second one is the impact of the passengers with the car's interior.

The main answer to the question is "a)

Both of these collisions are responsible for the injuries of the passengers and the extent of damage to the car. In the first collision, the car's energy is absorbed by the object or surface it collides with, causing damage to the car and the passengers inside.

The second collision is when the passengers' bodies collide with the interior of the car, including the steering wheel, dashboard, doors, windows, and so on. lt in death in severe cases.In conclusion, the main collision that happens during a crash is the impact of the car with the object, which causes damage to the car and the passengers inside.

In a car crash, two collisions occur. The impact of the car with the object it hits, and the impact of the occupants with the interior of the car. The aim is always to lengthen these collisions to reduce the forces involved, hence reducing injuries.

During a car crash, there are primarily two collisions that happen. The first collision is the impact of the car with the object. This could be another vehicle, a tree, or a wall. The momentum of the car changes during this time, leading to an abrupt stop or change in direction. The force exerted on the car will be less if this collision time is prolonged, which is why cars are manufactured to crumple upon impact, resulting in a lengthier, less forceful collision.

The second collision occurs between the occupants of the car and the interior of the car. When the car abruptly stops or changes direction, the passengers continue to move at the original speed due to inertia. This might lead to impacts with the dashboard, windscreen, or seat in front. To decrease the force acted upon the bodies of the passengers during this second collision, car safety equipment such as seatbelts and airbags are used. These gadgets increase the collision time, hence reducing the force with which the passengers might collide with the car's interior.

Therefore, the correct response to your question would be the impact of the car with the object.

Answer:

The direction of friction force is toards north.

Explanation:

A tool box is at rest on the back of a track. The truck is accelerating towards north.

As the frame of reference is acceleratinf so it is a non inertial frame  of reference.

Thus, teh toolkit experineces a pseudo force towards the south direction.

According to the question, the toolbox is at rest so the fiction force is balances by teh psheudoforce, and thus teh friction force is acting toards north.

so the resulting force of all the 3 forces is 11.7 N.

As shown in the figure below ther is 3 forces \(F_1 ,F_2 ,F_3\) are the forces so that the diagram is along the directions given in the question

so \(F_1\) = 3 j^ ( where j^ is unit vector along y axis)

\(F_2\) = 6 cos 45  i^ + 6 sin 45 j^ ( where i^ is unit vector along x axis)

\(F_3\)  = - 5 sin 30 i^ + 5 cos 30 j^

so the resultant force = \(F_1+ F_2 +F_3\)

=> 3 j^ + 4.24 i^ + 4.24 j^ + 4.33 j^ - 2.5 i^

=> 1.74 i^ + 11.57 j^

so resultant force = \(\sqrt{1.74^2 + 11.57^2}\)

=> \(\sqrt{136.89}\)

=> 11.7 N

so the resulting force of all the 3 forces is 11.7 N
