Option (ii) B is the correct option. The object on the moon has greater mass.

To resolve this, utilize the formulas Force = Mass * Acceleration.

The equation can be used to find the mass given the force in Newtons, using 9.8 m/s² for the acceleration of gravity of the earth and 1.6 m/s² for the moon.

Calculating the mass on earth:

30 N = 9.8 m/s² * mass

This results in a mass of 3.0 kg for the object on Earth.

Calculating the mass of the moon:

30 N = 1.6 m/s²2 * mass

Thus, the moon's object has a mass of 19. kg.

This can be explained by the fact that the earth has a stronger gravitational pull than the moon, producing more force per kilogram of mass. As a result, the moon's mass must be bigger to produce the same amount of force at a lower acceleration from gravity (1.6 m/s² vs. 9.8 m/s²).

During an experiment, a toy car accelerates forward for a total time of 5 s. Which of the following procedures could a student u
levacccp [35]

Answer: B

Explanation: The motion sensor will measure the speed (velocity) of the car. Since the mass of the car has been measured, we can use formulas to calculate the average force.

Average net force = mass × acceleration

The mass of the toy car is measured first and noted

To calculate the velocity,

the car starts from rest since the velocity is associated with the distance and time after 5s.

Acceleration = velocity/time

With that the acceleration can be found.

acceleration is defined as change in velocity per unit time.

Then,

Force = mass × acceleration

Option B is the best answer

A Plane crashes into the side of a mountain. If the crash took place over 9
Julli [10]

Given parameters:

Duration of crash = 9min

Velocity before crash = 2000 yards per second

Unknown:

Acceleration of the plane = ?

Solution:

Acceleration is the change of velocity with time.

  Acceleration  = \frac{V - U}{t}

where v is the final velocity

          u is the initial velocity

          t is the time taken

We need to convert the time into seconds from min;

                      60s  = 1 min

                                So, 9min = 60 x 9 = 540s

So input the parameters and solve;

                  Acceleration = \frac{2000 - 0 }{540}  = 3.7yards/s²

The acceleration of the plane is 3.7yards/s²

Flash floods can cause vehicles to float and fill with water, trapping and drowning people. while especially dangerous at night
almond37 [142]

Answer:

Option (C)

Explanation:

Flash flood refers to the sudden flood that occurs in a particular area due to the heavy and excessive amount of rainfall, often accompanied by thunderstorms within a few hours. It releases a huge amount of water due to the failure of natural levee as well dam. They are very devastating. During flash flood, the water exerts a massive force which can make vehicles float over water. The <u>six inches of water</u> that flows over an area has the capacity to lift the tyres of small vehicles and carry hem further away.

Thus, the correct answer is option (C).
