Use the formula
Heat= mass x specific heat x temperature increase
(1) acceleration, a = 4 m/ (2) acceleration of 10 N, = 1 m/ and acceleration of 30 N, = 3 m/
Explanation:
- Here, the acceleration of the object could be found using the equation derived in the second law of motion. The equation is given as, F = ma where m is the acceleration of the object, m is the mass of the object and F is the applied on the object.
- Let be the acceleration for force 10 N, to find acceleration rearrange the equation to a = . When we substitute 10 N force and 10 kg mass of the box in the equation. We will get = 1 m/
- Let be the acceleration for force 30 N, to find acceleration rearrange the equation to F = . When we substitute 30 N force and 10 kg mass of the box in the equation. We will get = 3 m/
- To find the combined, just add the force and substitute in the above equation. Hence, a = 4 m/
D all of the above

To calculate charge(Q) through a point, we multiply the current(I) with time (t)
Thus, Q= It
Therefore, t must be in SI units which gives 60*10 seconds.
Q=0.25A*600s= 150 coulombs.
Answer: Yes.
Explanation: Work in physics is defined as a force causing the movement—or displacement—of an object. In this case your eyes blinking, even though it was a very quick movement that didn't require much effort or energy, is still an example of your body at work.
