Because your body heat might change the temperature
Force of a crate : 300 N
<h3>Further explanation</h3>
Given
0.25 meters wide and 1.5 meters long
Pressure = 800 Pa
Required
Force
Solution
P = F/A
A = 0.25 x 1.5
A = 0.375 m²
P = 800 Pa = 800 N/m²
Input the value :
F = P x A
F = 800 N/m² x 0.375 m²
F = 300 N
Answer:
Elements are made up of only one type of atom. Each element has a unique chemical symbol. Elements can be identified by their atomic number.
Answer:
Force of friction is (-30 N).
Explanation:
The force applied on the box across the floor is 30 N.
The force of gravity is (-8 N) and the the normal force is 8 N.
It is based on Newton's third law of motion. Newton's third law of motion states that the force acting on object 1 to object 2 is equal in magnitude of the force from object 2 to 1 but in opposite direction.
Here there is force of 30 N is applied in horizontal direction. The frictional force act in opposite direction. So, the force of friction is -30 N so that box across the floor.
Answer:
watts are units of power, kilowatt-hours are units of energy
Explanation:
1 kilowatt-hour is = to 1000 watts used for 1 hour
