Answer:
The height at point of release is 10.20 m
Explanation:
Given:
Spring constant : K= 5 x 10 to the 3rd power n/m
compression x = 0.10 m
Mass of block m= 0.250 kg
Here spring potential energy converted into potential energy,
mgh = 1/2 kx to the 2 power
For finding at what height it rise,
0.250 x 9.8 x h = 1/2 x 5 x 10 to the 3 power x (0.10)to the 2 power) - ( g= 9.8 m/8 to the 2 power
h= 10.20
Therefore, the height at point of release is 10.20 m
Answer:
3 j
Explanation:
12.0 kilo / 4.00 meters = 3 j
I don't know about 1 but I know you should check 2 & 3 definitely
Answer:
The correct answer is: A HARD DISK
Explanation:
Magnetic Disc stores data of different types and formats that can always be edited or erased at any time. An example of a Magnetic Disc is a Hard Disk.
A hard disk is a type of magnetic storage device inside a computer that store data magnetically usually for the long-term and it could store a large volume of data, though that depends on the size, because it comes in various size. However, it generally allows stored data to be retrieved easily.
Answer:
Actually, there is no force (felt by the object) acting on the object.
It is similar to an object in orbit around the earth (weightlessness)
F = M a describes the motion of the particle where
M a = M g where the acceleration of the particle is equal to the force of gravity acting on the particle
From an external view the only force acting on the particle is M g and it produces an acceleration of M g
