Answer:
Resultant vector is the sum of two or more vectors
Answer:
124.88 km/h
34.69 m/s
Explanation:
1633.8 km = 1633800 m
13 hours 4 minutes 58 seconds = 13 + 4/60 + 58/3600 = 13.083 hours
13 hours 4 minutes 58 seconds = 13*3600 + 4*60 + 58 = 47098 seconds
So the average speed in km/h is
1633.8 / 13.083 = 124.88 km/h
The average speed in m/s is
1633800 / 47098 = 34.69 m/s
Answer:
Distance between Venus and Sun is 1.0864x10^11 m
Explanation:
Data
T1 (Total time taken by earth to rotate around sun)=365 days
T2 (Total time taken by venus to rotate around sun)=225 days
R1 (Radius b/w Sun and earth)=1.5x10^11m
R2(Distance between Venus and Sun)=?
Solution
Apply Kepler Law
(R2)^3/(R1)^3=(T1)^2/(T2)^2
(R2)^3/(1.5x10^11)^3=(225^2)/(365^2)
R2=1.0864x10^11m
Answer:
Explanation:
Given that,
Mass of student 1, m₁ = 65 kg
Mass of student 2, m₂ = 70 kg
The distance between the students, d = 3 m
We need to find the magnitude of the gravitational force between the two students. The formula for the magnitude of the gravitational force between two masses is given by :
So, the gravitational force between the two students is 
.
It would be B because they are just an explanation of what happens during a experiment
