Answer:
- Time delta is associated with difference in wavelengths
Explanation:
When pulsating radio waves consisting of different wavelengths pass through the ionized gas in interstellar space, the fast oscillating radio waves travel relatively faster than the slowly oscillating radio waves. As a result radio waves get dispersed and there is a time difference between the radio waves with different wavelength when the pulses arrive.
Answer:
Explanation:
Let's start by writing the equations of the forces along the two directions:
- Vertical:
where
N is the normal reaction
is the angle between the road and the horizontal
(mg) is the weight of the car, with m being its mass and g the acceleration of gravity
- Horizontal:
where
v is the speed of the car
r is the radius of the turn
Dividing the 2nd equation by the 1st one, we get:
In this problem:
(radius of the turn)
is the speed
Substituting, we find:
Electrical because without it, the hairdryer wouldn’t turn on. Thermal and sound are types of energy that are released after turning it on.
