Hydrostatic pressure is the pressure exerted by an incompressible fluid (a liquid) at a given point, due to the weight of the fluid above it. Atmospheric pressure is the pressure exerted on a surface by the weight of the atmosphere (a compressible fluid) above it.
The density of lead is 11.30 g/cm^3
Given the following data:
- Length = 4.50 cm
- Width = 5.20 cm
- Height = 6.00 cm
- Mass of lead = 1587 g
To find the density of lead;
First of all, we would determine the volume of the block of lead by using the formula;
Substituting the values into the formula, we have;
Volume = 4.50 * 5.20 * 6.00
Volume = 140.4 cm^3
Next, we find the density of lead;
Substituting the values into the formula, we have;
Density = 11.30 g/cm^3
Therefore, the density of lead is 11.30 g/cm^3

Answer: Wind follows a pattern because the Earth is spinning in one motion. If we were spinning in one way then another we would have one day go by then the spinning cycle would change and we would have to go through that day all over again, it would not be logical because then we would be in the same season as well, we would be in one season for the rest of our lives until we died.

Given that,
Mass of a ball = 300 kg
To find,
The gravitational force acting on the ball.
Solution,
The force acting on the ball is force of gravity. It is equal to the weight of the ball.
W = mg
Substitute the value of m and g in the above formula
W = 300 kg × 10 m/s²
= 3000 N
Therefore, the ball attracts with a force of 3000 N.

4 Amperes
Explanation:
At 600 Volts, a current of 4 amperes can pass through the body causing burns to internal organs.
Answer:
The acceleration is 14.28 km/h^2
Explanation:
Step one:
Given data
initial speed u= 0 km/h
final speed v= 140km/h
time t= 9.8 seconds
Required
The acceleration of the car
Step two:
From a= v-u/t
substitute
a= 140-0/9.8
a=140/9.8
a=14.28 km/h^2
Given that,
Mass of a boy = 50 kg
The coefficient of static friction = 0.68
To find,
Let us assume we need to find the maximum static friction between the boy and the ground.
Solution,
The formula for the maximum static friction between the two objects is given by :
Where
N is normal force
Substitute all the values,
Therefore, the maximum static friction between the boy and the ground is 340 N.
