An object, accelerating from rest at a constant rate, travels over 28 m in 11 s. What is its final velocity?
Paul [167]

Answer:

answer is 3

Explanation:

by using s= [(v+ u)/2] x t

28= (v+ 0)/2 x 11

v= 5.09 ms^-1

Based on the law of conservation of energy, how can we reasonably improve a machine’s ability to do work?
MrMuchimi

D. Redefine the machine’s system boundaries.

The Law of Conservation of Energy states that energy can't be created not destroyed. Energy, however, can be changed from one form to another. The law applies to isolated systems only. By redefining and expanding the system (including all factors affecting it) , the machine's ability to do work should improve.

A student is about to sled down a hill. He stands on a hill which is 30 meters tall and he weighs 40kg what is his GPE
PolarNik [594]

Answer:

11760J

Explanation:

Given parameters:

Height of hill  = 30m

Weight  = 40kg

Unknown:

Gravitational potential energy  = ?

Solution:

To find the gravitational potential energy, it is the energy due to the position of a body;

     G.PE  = mgh

m is the mass

g is the acceleration due to gravity

h is the height

 Now insert the parameters and solve;

      G.PE = 40 x 9.8 x 30  = 11760J

Suppose that we replace the aluminum with a mystery metal and repeat the experiment in the video. As in the video, the mass of t
dimaraw [331]

Answer:

b) one-third as great.

Explanation:

As we know that same heat is supplied in this experiment

so we will have

Q = ms\Delta T

now we know that both are initially at same temperature

then their final temperatures are

T_1 = 40 degree

T_2 = 80 degree

now we have

m_1s_1 (40 - 20) = m_2s_2(80 - 20)

so we have

m_2s_2 = \frac{20}{60} m_1s_1

so heat capacity of mystery metal is 1/3 times that of water
