Answer:
due to heaviness
Explanation:
because metal is heavier than water
Answer:
O An increase in the temperature will increase the pressure.
Explanation:
Decrease in volume, more collisions, increase in temperature, more particles: all of these increase the pressure.
Answer: O An increase in the temperature will increase the pressure.
Answer:
No, gravitational force is a force having infinite range. It only reduces to an extent that astronauts cannot feel it.
Explanation:
Answer:
a. Net force = 40 Newton.
b. Acceleration = 8m/s²
Explanation:
Given the following data;
Force on postive x-axis = 90N
Force on negative x-axis = 50N
Mass = 5kg
a. To find the net force;
Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.
The net force is equal to the difference between the two forces applied because they are acting in opposite directions.
Net force = 90 - 50
Net force = 40N
b. To find the acceleration;
Acceleration = net force/mass
Acceleration = 40/5
Acceleration = 8m/s²
