Find the pressure exerted by a force 8000 newton's on an area of 25m^2. Give your answer in newton's/n^2
1 answer:
The pressure exerted by this force is equal to 320 .
<u>Given the following data:</u>
- Force = 8000 Newton.
- Area = 25
.
To calculate the pressure exerted by this force:
<h3>How to calculate pressure.</h3>Mathematically, pressure is given by this formula:
<u>Where:</u>
- P is the pressure.
- F is the force.
- A is the area.
Substituting the given parameters into the formula, we have:
P = 320 .

Answer:
<h3>0.445</h3>Explanation:
In friction, the coefficient of friction formula is expressed as;
Ff is the frictional force = Wsinθ
R is the reaction = Wcosθ
Substitute inti the equation;
Given
θ = 24°
Hence the coefficient of kinetic friction between the box and the ramp is 0.445
Answer:
False statement = There must be a non-zero net force acting on the object.
Explanation:
An object is moving at a constant speed along a straight line. If the speed is constant then its velocity must be constant. We know that the rate of change of velocity is called acceleration of the object i.e.
a = 0
⇒ The acceleration of the object is zero.
The product of force and acceleration gives the magnitude of force acting on the object i.e.
F = m a = 0
⇒ The net force acting on the object must be zero.
So, the option (a) is not true. This is because the force acting on the object is zero. First option contradicts the fact.
