The average radius of Mars is 3,397 km. If Mars completes one rotation in 24.6 hours, what is the tangential speed of objects on
2 answers:
Answer:
Tangential speed of objects on the planet’s surface = 241 m/s
Explanation:
Speed is given by the ratio of distance traveled to the time.
Radius of mars, r = 3397 km = 3.397 x 10⁶ m
Distance traveled = 2πr = 2 x π x 3.397 x 10⁶ = 2.13 x 10⁷ m
Time taken = 24.6 hours = 24.6 x 60 x 60 = 88560 s
Tangential speed of objects on the planet’s surface = 240.51 m/s = 241 m/s

Answer:
14.0 m
25.1 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Distance traveled in the reaction time
Distance = Speed × Time
Distance in which the car will stop is 10+20 = 30.0 m
So, the car will not hit the deer
Distance between the car and deer is 44-30 = 14.0 m
Maximum speed of the car by which it will not hit the deer is 25.1 m/s
Answer:
The value is
Explanation:
From the question we are told that
The wavelength is
The velocity is
The mass of electron is
Generally the energy of the incident light is mathematically represented as
Here c is the speed of light with value
h is the Planck constant with value
So
