20 kg*m/s because there is 2 kg mass and 10 m/s so you can multiply.

I WILL GIVE BRAINLIEST....<br>Determine the value of F...​
aleksley [76]
F should be 10. If The Whole top is 50cm, then we should subtract 10n and 30n which gives us 10.

Or it could be 15 if both top and bottom are 25. 10+15= 25.

Objects 1 and 2
sattari [20]

Answer:

12 units

Explanation:

Original F = C q1q2/r^2    now change the parameters

  New F = C  1/3 q1  2 q2  / (2r)^2

              =  2/12  C q1q2/r^2    <=======the new force is 1/6 of original

1/6 * 72 = 12 units

A block oscillating on a spring has period T = 2.8 s . (Note: You do not know values for either m or k. Do not assume any partic
olasank [31]

Answer:

Part a)

T = 3.96 s

Part b)

T = 1.98 s

Part c)

T = 2.8 s

Explanation:

As we know that time period of spring block system is given as

T = 2\pi\sqrt{\frac{m}{k}}

T = 2.8 s

Part a)

If the mass of the block attached is doubled

then we will have

T' = 2\pi\sqrt{\frac{2m}{k}}

T' = \sqrt2 T

T' = 3.96 s

Part b)

If the spring constant is doubled

then we have

T' = 2\pi\sqrt{\frac{m}{2k}}

T' = \frac{T}{\sqrt2}

T' = 1.98 s

Part c)

If the amplitude is halved but mass and spring constant will remain the same

so here we know that time period does not depends on Amplitude

so we will have

T = 2\pi\sqrt{\frac{m}{k}}

T = 2.8 s
