Average speed of the car is 11 m/s
Explanation:
- Speed is calculated by the rate of change of displacement.
- It is given by the formula, Speed = Distance/Time
- Here, distance = 2155 m and time = 195.9 s
Speed of the car = 2155/195.9 = 11 m/s
Answer:
Acceleration of the crate is 0.362 m/s^2.
Explanation:
Given:
Mass of the box, m = 40 kg
Applied force, F = 15 N
Angle at which the force is applied, 
= 15°
We have to find the magnitude of the acceleration.
Let the acceleration be "a".
FBD is attached with where we can see the horizontal and vertical component of force.

The volume of the jet fuel is 1.213 x 10⁵ cm³.
<h3>What is density?</h3>
Density is a physical property that measures the ratio of mass to volume occupied by an object.
Density = mass/volume
Volume = mass/density
<h3> Volume of the jet fuel</h3>
The volume of the jet fuel is calculated as follows;
Volume = (97500 g)/(0.804 g/cm³)
Volume = 1.213 x 10⁵ cm³
Thus, the volume of the jet fuel is 1.213 x 10⁵ cm³.

Answer:
The Kelvin temperature scale is used by scientists because they wanted a temperature scale where zero reflects the complete absence of thermal energy. ... Many quantum mechanical properties are washed out by the thermal agitation that occurs in materials.
