Explanation:
Though the diagram that is mentioned in the questions is not given. I have given general information related to the Earth's magnetic axis with respect to geographic/rotational axis.
Axis is an imaginary line around which a body rotates. The rotational axis of the Earth enters into and exits from the Earth at two points namely: North and South pole.
We know that the Earth behaves like a huge bar magnet so just like the bar magnet it must also have magnetic axis and poles. Earth has north magnetic pole and south magnetic pole. It has a strong magnetic field as well known as magnetosphere.
The interesting point about magnetic axis is that it is not same as rotational axis. In fact it makes an angle with the rotational axis. This is known as magnetic inclination. This inclination varies at different points on Earth.
Another interesting point is that the geographic and magnetic poles are opposite. That means near the geographic north pole we have the magnetic south pole and vice versa.
Answer:
2763.53411 m/s
Explanation:
M = Mass of Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 m
= Launch velocity
= Final velocity = 500 m/s
h = Altitude = 400 km
m = Mass of satellite
As the energy of the system is conserved we have
The launch speed of the satellite should be 2763.53411 m/s
Answer:
ambulance speed is 30.38 m/s
Explanation:
given data
hear frequency = 510 Hz
pass frequency = 427 Hz
speed of sound = 343 m/s
to find out
ambulance speed
solution
we consider here ambulance speed is v
so when we hear frequency velocity equation will be
510 = 343f / ( 343 - v ) ...........................1
and when ambulance pass velocity equation will be
427 = 343f / ( 343 + v ) ...........................2
so from equation 1 and equation 2
= 510 / 427
= 510 / 427
solve it we get
v = 30.38 m/s
so ambulance speed is 30.38 m/s
Answer:
Melting
Explanation:
The states of matter changed by the induction of heat from a lava lamp is by melting. For example, if you put a ice cube which is a solid under a lava lamp it will melt and become a liquid.
