Here i hope this helps, let me know if you need clarification on anything :)
Fact. Using lift equipment would take longer.
The magnitude of the total displacement is 1000 m
Explanation:
Displacement is a vector quantity connecting the initial position and final position of motion of an object.
The magnitude of the displacement is therefore the distance in a straight line between the initial and final position of motion.
The person in the problem has the following motions:
500 meters due east
866 meters due north
The two motions are perpendicular to each other, so they form the sides of a right triangle, of which the hypothenuse corresponds to the magnitude of the total displacement.
Therefore, the magnitude of the displacement can be simply found by using Pythagorean's theorem:

Answer:
Kinetic Theory states that pressure is not cause by molecule that push molecule to each other
Explanation:
Kinetic Theory
it is also known as kinetic molecular theory or the collision theory
Kinetic theory explain you property of gas such as
(1) pressure, (2) temperature, (3) volume
Kinetic Theory states that pressure is not cause by molecule that push molecule to each other and pressure is caused by molecule colliding with the each other and with the container
3 component of
kinetic theory are
-
when the molecules collide, there no energy is gain or lost
- In the gas molecule take approx negligible amount of space
- molecules are in constant and linear motion
Answer:
We know that potential energy of a body;
= mass(m)× gravitational acceleration(g) × height(h)
Lets find out the mass of the body
P.E. = mgh
=> 6500J = mass × 9.8m/s^2 × 12m
=>6500J = mass × ( 9.8 × 12 ) × ( m/s^2 × m)
=> 6500 Nm = m × 117.6 × m^2 / s^2
=> 6500/117.6 Ns^2/m = mass [°.° Ns^2/m = kg]
=> 55.272 Kg = mass
Therefore the mass of the body = 55.272 kg ~ <em>6</em><em>0</em><em> </em><em>k</em><em>g</em><em> </em>(Ans)
Hope it helps you
