Answer:
The acceleration is -9.8 m/s²
Explanation:
Hi there!!
When you throw a ball upward, there is a downward acceleration that makes the ball return to your hand. This acceleration is produced by gravity.
The average acceleration is calculated as the variation of the speed over time. In this case, we know the time and the initial and final speed. Then:
acceleration = final speed - initial speed/ elapsed time
acceleration = -4.3 m/s - 4.3 m/s / 0.88 s
acceleration = -9.8 m/s²
Answer: hello your question is incomplete attached below is the complete question
answer : 1/2 KD^2 ( option A )
Explanation:
P.E ( potential energy ) = mgd
In case 1 P.E = 0 i.e. mgd = 0
Given that in case 2 the Mass M had moved through the Distance D by the compression of the spring
<u>The potential energy of the M in case 2 </u>
= P.E of M at rest + P.E of the spring
= 0 + 1/2 KD^2
Answer:
you cant caculate this because there is no question
Explanation:
Explanation:
the unit of area is called a derived unit because it is made of two fundamental unit metre and metre.
Answer: 0.125
Explanation:
Given that the
Object height U = 24.8 cm
Image height V = 3.09 cm
Magnification M is the ratio of the image height to the object height. That is, divide the given image height by the given object height.
M = V/U
Substitute V and U into the formula above.
M = 3.09/24.8
M = 0.125
Magnification is therefore equal to 0.125 approximately
