The formula for speed id speed is equal to distance/time
so to 5.0/0.01=500m/s.
Hence, the horizontal velocity of the rover is 1.73 m/s
Answer:
150000000

49050000 N/C
Explanation:
q = Charge = 24 pC
m = Mass of honeybee = 0.12 g
E = Electric field = 100 N/C
g = Acceleration due to gravity = 9.81 m/s²

Number electrons is

The number of electrons added or removed was 150000000
Force is given by

The ratio is

The ratio is 
Balancing the forces we get

The electric field required is 49050000 N/C
Answer:

Explanation:
according to snell's law

refractive index of water n_w is 1.33
refractive index of glass n_g is 1.5


now applying snell's law between air and glass, so we have


![\beta = sin^{-1} [\frac{n_g}{n_a}*sin\alpha]](https://tex.z-dn.net/?f=%5Cbeta%20%3D%20sin%5E%7B-1%7D%20%5B%5Cfrac%7Bn_g%7D%7Bn_a%7D%2Asin%5Calpha%5D)
we know that 

Answer:
Explanation:
To calculate the red shift you use the following formula:

\tetha: angle between the observer and the motion of the body
v: speed of the body
c: speed of light
for motion with angle 90° (transversal motion):

- A red dwarf moving away from Earth at 39.1 km/s :

- A yellow dwarf moving transversely at 15.1 km/s (angle = 90°):

- A red giant moving towards Earth at 23.3 km/s (angle = 0°):

- A blue dwarf moving away from Earth at 25.9 km/s
- A red dwarf moving transversely at 14.1 km/s
