To find black holes in space, scientists use telescopes to study visible light, X-rays, and radio waves. When gas orbits a black hole, it gets very hot and starts emitting X-rays and radio waves. Through special telescopes, the area surrounding the black hole looks really bright.

Monica [59]

Answer:

The main difference in these two movements is that the first is a pure swing movement and the followed form a wave travels from the beach

Explanation:

The movement in the two parts is very different, when the surf zone has passed it is in a deeper part of the water where the seabed does not rise much, therefore due to the movement of the waves there is an upward oscillatory movement and descending, in this movement there is no horizontal displacement.

When it is within the southern zone, there is a rapid rise of the sea floor, which generates a horizontal movement, having a traveling wave, therefore your movement is more complicated, you can have some oscillating movement on the axis and, but in addition to this you have a horizontal movement that reaches you towards the beach, forming a Traveling wave.

The main difference in these two movements is that the first is a pure swing movement and the followed form a wave travels from the beach

BabaBlast [244]

Answer:

The maximum pressure is 10 V from across condenser.The highest charge mostly on condenser. 
Vc  = 10 x 1mf

= 10 ^ - 5C

The time it takes for the condenser to be 5 V different.        
Thus we have, 0.69 x 10 ^ - 3 seconds.

Two tuning forks struck simultaneously produce a beat with a frequency of 2 Hz. The frequency of one fork is 364 Hz. What are th
Kitty [74]

Answer: If the other two frequencies are F and F1 then;

F-364=2

F=364+2

F=366Hz

364-F1=2

F1=364-2

F1=362Hz

Hence the two possible frequencies are 362Hz and 366Hz

Yuliya22 [10]

Answer:

-6.44 m/s²

Explanation:

Given:

Δx = 60 m

v₀ = 27.8 m/s

v = 0 m/s

Find: a

v² = v₀² + 2aΔx

(0 m/s)² = (27.8 m/s)² + 2a (60 m)

a = -6.44 m/s²
