Answer:
Force = -1161.6 Newton
Explanation:
Given the following data;
Initial velocity, u = 44m/s
Distance ,s = 12.5cm to m = 12.5/100 = 0.125m
Mass = 0.15kg
To find the acceleration;
We would use the third equation of motion;
V ² = U² + 2as
0² = 44² + 2*a*0.125
0 = 1936 + 0.25a
0.25a = -1936
a = -1936/0.25
Acceleration, a = -7744m/s2
Force = mass * acceleration
Substituting into the equation, we have;
Force = 0.15 * (-7744)
Force = -1161.6 Newton
The value of its force is negative because the glove decreases the velocity of the ball.

Answer:
F = 1.24*10^4 N
Explanation:
Given
Depth of the ship, h = 25 m
Density of water, ρ = 1.03*10^3 kg/m³
Diameter of the hatch, d = 0.25 m
Pressure of air, P(air) = 1 atm
Pressure of water =
P(w) = ρgh
P(w) = 1.03*10^3 * 9.8 * 25
P(w) = 2.52*10^5 N/m²
P(net) = P(w) + P(air) - P(air)
P(net) = P(w)
P(net) = 2.52*10^5 N/m²
Remember,
Pressure = Force / Area, so
Force = Area * Pressure
Area = πr² = πd²/4
Area = 3.142 * 0.25²/4
Area = 3.142 * 0.015625
Area = 0.0491 m²
Force = 0.0491 * 2.52*10^5
F = 12373 N
F = 1.24*10^4 N
So when making structures you have to have squares rectangles right and a triangle and another triangle equals a square so thats all there is to it
Answer:
C, weathering by the water.
Explanation:
While in the river, it scraps againsts other rocks and things, which causes it to change shape. For example be smoother and round.
