Answer:

x = 3.84\times 10^{5}\,km

This delay affect conversations in the sense that recipient will be receive the message just 2.56 seconds after the message was sent.

Explanation:

The laser pulse has an ondulatory nature as electromagnetic wave, which can travel in the void. Speed of light is constant and distance between Earth and the Moon is:

x = 0.5\cdot c\cdot \Delta t

x = 0.5\cdot (3\times 10^{5}\,\frac{km}{s})\cdot (2.56\,s)

x = 3.84\times 10^{5}\,km

This delay affect conversations in the sense that recipient will be receive the message just 2.56 seconds after the message was sent.

A father fashions a swing for his children out of a long rope that he fastens to the limb of a tall tree. As one of the children
trasher [3.6K]

Answer:

The centripetal acceleration of the child at the bottom of the swing is 15.04 m/s².

                     

Explanation:

The centripetal acceleration is given by:

a_{c} = \frac{v^{2}}{r}

Where:

v^{2}: is the tangential speed = 9.50 m/s

r: is the distance = 6.00 m

Hence, the centripetal acceleration is:

a_{c} = \frac{v^{2}}{r} = \frac{(9.50 m/s)^{2}}{6.00 m} = 15.04 m/s^{2}

Therefore, the centripetal acceleration of the child at the bottom of the swing is 15.04 m/s².

I hope it helps you!

Can’t be Carnivore because deer don’t eat meat

Same with tertiary

They do eat plants. So it would have to be the last one
