Answer:
Explanation:
M = Mass of Earth
G = Gravitational constant
R = Radius of Earth
The acceleration due to gravity on Earth is
On new planet
Dividing the two equations we get
The acceleration due to gravity on the other planet is
Answer:
6 m/s²
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 30 m/s
Time (t) = 5 s
Acceleration (a) =..?
Acceleration is defined mathematically as:
Acceleration (a) = Velocity (v) /time (t)
a = v /t
With the above formula, we can obtain the acceleration of the object as follow:
Velocity (v) = 30 m/s
Time (t) = 5 s
Acceleration (a) =..?
a= v/t
a= 30/5
a = 6 m/s²
Therefore, the acceleration of the object is 6 m/s² due East.
as we know tha momentum is product of mass and velocityi.e p=mv but here in this question velocity changes from 5m/s to 20 m/s so here formula becomes
p=(final velocity -initial velocity )mass
so (20-5)6=90kgm/s ANS
Answer:
Harish went 1.92 Km in 2 minutes.
Explanation:
Harish is running at 16 m/s (Meters per second) and we need to find how far he goes in 2 minutes.
We can use this formula to calulate the distance:
m/s x time
We know that Harish is going 16m/s so let's plug that in:
16 (m/s) x time
We also should know that 2 minutes is 120 seconds - Let's plug that in too:
16 (m/s) x 120 (Seconds)
Now we calculate:
16 x 120 = 1920
Harish went 1,920 meters in 2 minutes.
Even though we have a correct answer, we can still make it easier to read by converting meters into kilometers.
1 Kilometer (Km) is equal to 1,000 meters.
All we need to do now is divide 1,920 by 1,000 and that will gove us our simplified answer of:
1.92 Km
Answer:
Speed of sound is 30.91m/s
Explanation:
Speed is given by:
Speed = distance travelled / time taken
Given:
Distance travelled = 1020m
Time taken = 33seconds
Speed = 1020m/33s
Speed = 30.91m/s
