Answer:
Explanation:
The torque of a force is given by:
where
F is the magnitude of the force
d is the distance between the point of application of the force and the centre of rotation of the system
is the angle between the direction of the force and d
In this problem, we have:
, the force
, the distance of application of the force from the centre (0,0)
, the angle between the direction of the force and a
Therefore, the torque is
Answer:
3.3kg
Explanation:
Given parameters:
Spring constant = 400N/m
Extension = 8cm = 0.08m
Unknown:
Amount of mass the spring is supporting = ?
Solution:
To solve this problem:
F = kE
F is the force
k is the spring constant
E is the extension
So;
F = 400 x 0.08 = 32N
Mass;
Force = mass x acceleration due to gravity
32 = mass x 9.8
Mass = 3.3kg
The cold air increases pressure on the basketball, causing it to appear flat. When it warms up that pressure is taken off, so the basketball is at it's normal state.
Answer:
The density of salt water is more than that of density of fresh water, so so salt and fresh water makes a difference in floating of ships.
