A car traveled 60km in 45 min.What is the cars average speed in km/hr

Physics
1 answer:
sergey [27]2 years ago
5 0

Given that,

Distance = 60 km

Time = 45 min

To find,

The average speed of the car.

Solution,

Average speed of an object is equal to the total distance divided by total time taken.

45 min = 0.75 hour

It can be given as :

V=\dfrac{60\ km}{0.75\ h}\\\\=80\ km/h

Therefore, the average speed of the car is 80 km/hr.

A very slow motion of earth's axis that requires 26,000 years to complete is called ________.
agasfer [191]

The answer is axial precession. Axial precession refers to the very slow motion of the Earth’s axis, which almost requires twenty-six thousand (26,000) years to complete a full rotation. This Axial Precession is caused by the effects of gravitational pull from the Sun and the Moon towards the Earth.

If you stood on a planet with four times the mass of Earth, and twice Earth's radius, how much would you weigh?
nikdorinn [45]

Answer:

1/4 times your earth's weight

Explanation:

assuming the Mass of earth = M

Radius of earth = R

∴ the mass of the planet= 4M

the radius of the planet = 4R

gravitational force of earth is given as = \frac{GM}{R^{2} }

where G is the gravitational constant

Gravitational force of the planet = \frac{G4M}{(4R)^{2} }

                                                       =\frac{G4M}{16R^{2} }

                                                       =\frac{GM}{4R^{2} }

recall, gravitational force of earth is given as = \frac{GM}{R^{2} }

∴Gravitational force of planet = 1/4 times the gravitational force of the earth

you would weigh 1/4 times your earth's weight
