The shock wave from the meteoroid in the lower atmosphere has a Mach angle of 0.948°.
(a) The meteoroid's speed 
Air sound wave speed 
Speed of the shock wave in Mach 
Hence, 0.948° is the Mach angle of the shock wave from the meteoroid in the lower atmosphere.
<h3>What is the speed of the meteoroid?</h3>
A meteoroid's speed can be loosely broken down into three categories: slow, medium, and fast.
- Slow meteors move around the sun at a leisurely pace of about 32 kilometers per second (20 miles per second).
- Medium-speed meteors travel around the sun at approximately 50 kilometers per second (30 miles per second),
- while fast meteors zoom past at over 120 kilometers per second (75 miles per second)!

Answer:Wrap more turns of wire around the nail.
Explanation:The power of an electromagnet is directly proportional to the amount of electricity passing through that electromagnet.
Now,if they increase the number of rounds of the copper coil,the electricity conducting surface amount will also increase.
And that's why the electricity passing through that electromagnet will increase along with the electromagnetic power of that electromagnet.
• Increasing the battery voltage :
If they increase the battery voltage,the electricity which is passing through that electromagnet will also increase in amount .
And as discussed previously,the increasing amount of electricity will also increase the electromagnetic abilities of the electromagnet.
Hey there!
A sound wave is a<u> longitudinal wave</u>, meaning that the motion of the particles of the wave is parallel to the direction of the motion of the wave.
Hope this helps!
Answer:
Explanation:
Given
Maximum height H = 300m
Range (horizontal distance) = 380m
Required
Initial speed U and the angle of the ball when it was launched.
Range = U√2H/g
380 = U√2(300)/9.8
380 = U√600/9.8
380 = 7.8246U
U = 380/7.8246
U = 48.57m/s
The initial speed is 48.57m/s
b) Using the formula for calculating time of flight;
T = 2Usin theta/g
9 = 2(48.57)sin theta/9.8
9*9.8 = 97.14sin theta
88.2 = 97.14sin theta
88.2/97.14 = sin theta
sin theta = 0.9079
theta = sin^-1(0.9079)
theta = 65.23°
hence the angle when the ball was launched is 65.23°
If an object experiences no net force, its velocity will remain constant. The object is either at rest and the velocity is zero, or it moves in a straight line with a constant speed.
