xenn [34]3 years ago
4 0

Explanation:

Sound travels faster In solids than liquid than gases

Speed of sound is highest in solids, and higher in liquids and slower in gases. Example- Sound travels in air with the speed of 330 m/s, In steel it travels with a speed of 5920 m/s, In liquids it travels with a speed of 5000 m/s.

Hope this helps you

a car moving with a speed of 10 metre per second is accelerator at the rate of 2 metre per second square find its velocity after
STatiana [176]

a = ( v(2) - v(1) ) ÷ ( t(2) - t(1) )

2 = ( v(2) - 10 ) ÷ ( 6 - 0 )

2 × 6 = v(2) - 10

v(2) = 12 + 10

v(2) = 22 m/s

Triss [41]

Answer:

Their densities are different as well

Explanation:

Density is worked out by dividing mass by volume. If the mass was the same then the densities would be as well. But it's not.

A delta connection has a voltage of 560 V connected to it. How much voltage is dropped across each phase
SashulF [63]

Answer:

E_Phase = 560V

Explanation:

The computation of the voltage i.e. dropped across each phase is shown below:

Given that

The delta connection line voltage is

E_line = 560 V

And, in the case of delta connection, the line voltage would be equivalent to the phase voltage

That means

E_Phase = E_Line

= 560 V

Hence, the voltage i.e. dropped across each phase is

E_Phase = 560V
