When_____forces act on an object, they cause the object to move.A. Balanced B. Unbalanced C. friction D net B?

Answers

Answer 1

Answer: i think the answer is B coz whenever object is in unbalanced it moves

Answer 2

Answer: it is not balanced bc then it would be completely still, it would not be friction bc that's what keeps it going after it moves, so the correct answer is B because when it's unbalanced then it starts to move then the friction keeps it going on.

How far does a car travel as it accelerates from rest to 24 m/s in 6 seconds?

Answers

Answer:

$\boxed{\sf Distance \ travelled = 72 \ m}$

Given:

Initial velocity (u) = 0 m/s (Starts from rest)

Final velocity (v) = 24 m/s

Time taken (t) = 6 seconds

ToFind:

Distance travelled by car (s)

Explanation:

From equation of motion of object moving with uniform acceleration in straight line we have:

$\boxed{ \bold{s = ((v + u)/(2) )t}}$

By substituting value of v, u & t in the equation we get:

$\sf \implies s = ( (24 + 0)/(2) ) * 6 \n \n \sf \implies s = (24)/(2) * 6 \n \n \sf \implies s = 12 * 6 \n \n \sf \implies s = 72 \: m$

$\therefore$

Distance travelled by car (s) = 72 m

When a magnet is cut into two parts, then both parts will have a south and north pole because magnetic fields lines are continuous and always formed closed loops.

For an isothermal process, the work done by or on a system of ideal gas is equal to the change in what? A. The work done is equal to the change in internal energy.
B.The work done is equal to the change in heat energy.
C.The work done is equal to change in entropy.
D.The work done is equal to the change in pressure.

Answers

For an isothermal process, the work done by or on a system of ideal gas is equal to the change in heat energy. The correct option is B.

What is isothermal process?

The process in which the temperature remains constant and other physical quantities are variable, is called the isothermal process.

From the first law of thermodynamics, the work done is the difference between heat supplied and change in internal energy of the system.

W = ΔQ - ΔU

For isothermal process, change in internal energy will be zero.

So, work done is equal to the change in heat energy.

Thus, the correct option is B.
