⭐Hey
⭐Here we can use the formula for the body that is in free fall state. .
⭐that is
↪V = underoot 2*g*h
↪So the velocity will be ...
↪V = underoot 2 * 10 * 100
↪V = underoot 2000
↪V = 20 *underoot 5
↪V = 20 ( 2.23)
↪V = 44.6 m/s
Answer:
a) Peak value = 20
b) Average value = 9.0
c) RMS value = 14.15
Explanation:
The peak-to-peak value = 40


c) The rms value

b) Average value over alternation of the sine wave
Force = mass * acceleration
15 = 2.1 * a
a = 15/2.1 = 7.143 m/s^2
Answer:
C) at right angles to the direction of the motion
Explanation:
The magnetic force exerted on a charged moving particle is given by

where
q is the charge of the particle
v is the velocity of the particle
B is the magnetic field intensity
is the angle between the direction of v and B
Moreover, the direction of the force is perpendicular to both v and B. In particular, the direction can be found by using the right hand rule:
- index finger: direction of the velocity
- middle finger: direction of the magnetic field
- thumb: direction of the force (if the charge is positive, otherwise the direction must be reversed if the charge is negative)
The answer is B.
The planet cannot be too hot or too cold it has to be the right distance from its sun to maintain life.
