Solar Radiation, The Solar Wind, and Gamma Ray Bursts
Hello,
To solve we need to know the formula for speed
The formula is D/T=S (Distance of time=speed)
Now all we have to do is plug in the numbers.
20/40= 1/2 or 0.5
SO the speed is 0.5 m/s
Have a great day!
The magnitude is 167.6cm and the angle (relative to the floor) of the displacement of p is 32.5 degree.
<h3>
What is displacement ?</h3>
A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions. It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.
A point's ultimate location in relation to its original position, or a displacement, can also be defined as a relative position. The instantaneous velocity of an object is the rate at which the displacement changes as a function of time when studying motions of objects throughout time.
Explanation:
a)
height = 2*r =2*45 cm = 90 cm
y = 1/2 * circumference
=1/2 * 2*pi*r
= pi*r
= pi*45
= 141.4 cm
displacement =sqrt ( height^2 + y^2)
= sqrt (90^2 + 141.4^2)
= 167.6 cm
Answer: 167.6 cm
b)
angle ,x = atan (height/y)
= atan (90/141.4)
= 32.5 degree
Answer: 32.5 degree

Answer:
High tides and low tides are caused by the Moon.
Explanation:
The Moon's gravitational pull generates something called the tidal force.
Answer: 12.5m
Explanation:
Given the following :
Flagpole makes 20 complete vibrations in 10 seconds
Velocity (V) of vibration = 25m/s
Find the wavelength of vibration (λ) =?
Frequency is number of complete oscillation per Second
Therefore ;
Frequency (F) = number of oscillations / time taken
F = 20 / 10 = 2Hz
Wavelength = Velocity / frequency
Wavelength = 25 / 2
Wavelength = 12.5m
