Work done is when a force is exerted to cause a displacement in a certain object. 
the equation for work done ;
work done = force applied * displacement of the object 
when the force applied is not in the same direction as that of the displacement of the object then the effect of the force is not its whole value. The force is then applied at an angle to that of the displacement of the object, then the resultant force is the force exerted* cos of the angle between force and displacement, in this instance the angle is 40 °.
the new equation is then;
work done = force cos 40° * displacement
after substitution,
work = 25 N * 0.76 * 50 m
         = 957.55 J
round it off
         = 9.6 *10² J
the correct answer is B

What force does it take to accelerate a 7.2 kg object 3.0 m/s^2.
grin007 [14]

Answer:

<h2>21.6 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 7.2 × 3 = 21.6

We have the final answer as

<h3>21.6 N</h3>

This is a form of energy representing the motion of the molecules which make up an object. A. Thermal Energy B. Kinetic Energy C
bija089 [108]

Answer:

Kinetic energy.

Explanation:

  • There are many kinds of energy. Some of them are kinetic energy, potential energy, thermal energy etc.
  • The energy that shows the motion of the object is called its kinetic energy.
  • Also, the sum of kinetic energy and the gravitational potential energy is called mechanical energy.
  • Out of the given options, kinetic energy is the form of energy that represents the motion of the molecules which make up an object.
  • Hence, the correct option is (B).

Many processes help to shape Earth’s surface. Starting with a rock, in what order would you expect the following Earth processes
GuDViN [60]
<span>Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. </span><span>All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. A rock is any naturally formed, nonliving, firm, and coherent aggregate mass of solid matter that constitutes part of a planet. i don't know if this is right but i hope it helps</span>
