1 answer:

6 0

Answer: YES.

Explanation: OK, lets say you have a basket of fruit, it has a large mass, and a large gravity, it takes more force to lift it up. now, if we try to carry it lets say, across the yard, its gonna be pretty heavy! now, when we put it in a wheel barrow, the force goes onto the wheels. it takes less force to move it.

A force of 450 N moves a body through 300 cm in the direction of force. Calculate the work

OlgaM077 [116]

Answer:

150J

Explanation:

Formula : Work done

Force x distance

work done = force x distance

Distance should be measured in meters

300÷100=3m

work done = 450 x 3

=150J

The gas sample has now returned to its original state of 1.00 atm, 20.0 ∘c, and 1.00 l. what will the pressure become if the tem

steposvetlana [31]

At a constant volume and number of moles of the gas the ratio of T and P is equal to some constant. At another set of condition, the constant is still the same. Calculations are as follows:

T1/P1 = T2/P2

P2 = T2 x P1 / T1

P2 = 473.15 x 1.00 / 293.15

P2 = 1.61 atm
