At the tip of the compass there is a magnet, in which the magnet responds
to a strong act of magnetism
B 10,000 - 30,000 K Blue-white stars
A 7,500 - 10,000 K White stars
F 6,000 - 7,500 K Yellow-white stars
G 5,000 - 6,000 K Yellow stars (like the Sun)
The lowest temperature stars are red while the hottest stars are blue. Astronomers are able to measure the temperatures of the surfaces of stars by comparing their spectra to the spectrum of a black body.
If the net force is zero, then there is no acceleration, which means no change in velocity. The velocity starts at zero, so it must remain at zero. Therefore, the object will not move.
Hi there!
Recall the equation for weight.
W = Weight (N)
M = Mass (kg)
g = acceleration due to gravity (m/s²)
The weight of an object depends upon its MASS and the strength of the GRAVITATIONAL field. We can solve for weight:
Velocity of Deidre and her dog is 2.11m/s.
<h3>What is velocity?</h3>
- Velocity is the rate of change of position of an object in a particular frame of reference
- Mathematically, velocity of an object = Displacement of the object/time taken
<h3>What is velocity of Deidre and her dog ?</h3>
- The distance covered by Deidre and her dog is 95 meter towards north.
- The time taken to cover the distance is 45 second.
- So velocity of Deidre and her dog =95/45
=2.11m/s
Thus , we can conclude that the velocity of Deidre and her dog is 2.11 m/s towards north .
