Several information's that are required to get to the answer of the question is already given in the question. It is important to write them down first and then start solving the problem.
Force = 400 newton
Mass = 100 kg
We already know that
Force = Mass * Acceleration
Then
Acceleration = Force/Mass
= 400/100
= 4 m / S^2
The acceleration of the object is 4 m/s$2. I hope the procedure is clear for your understanding. In future you can use this method for solving such questions.
Metals are malleable and ductile.
Metals are good conductors of heat and electricity.
Metals are lustrous (shiny) and can be polished.
Metals are solids at room temperature (except mercury, which is liquid).
Metals are tough and strong.
hope this helps!
Answer:
The magnet will not pick anything up because it has lost its magnetism
Answer:
Option C or the third option.
Explanation: Water is a renewable resource there is so much of it and it just keeps circulating through the system it doesn't run out.
Answer:
x = 4 m
Explanation:
For this exercise we must use the rotational equilibrium relationship, where we place zero at the turning point and counterclockwise rotations we will consider positive
as it indicates that the bar is in equilibrium, its center of mass coincides with the turning point, so the distance is zero and does not create torque on the system
∑τ = 0
W 3 - w x = 0
x = 3W / w
x = 3 Mg / mg
x = 3 M / m
let's calculate
x = 3 60/45
x = 4 m
