List 3 pieces of evidence for the Earth’s spherical shape

Physics
1 answer:
KATRIN_1 [288]3 years ago
3 0

Answer:

1.time zones

2.The coriolis effect

3. triangles

Explanation:

1. day and night happen at different times at different places; it's always day somewhere and night another.

2. the coriolis effect means freely moving things (like cannonballs or hurricane  winds) are deflected to the right - but only if your north of the equator if you're  south of the equator they're deflected left.

3. if you walk a certain distance and make three right angle you can successfully make a triangles with three 90 degree angles which is impossible on a flat surface.

An occupant of a car has a chance of surviving a crash if the deceleration during the crash is not more then 30 g. Calculate the
sweet [91]

Answer:

20,850 N

Explanation:

We can solve the problem by using second Newton's Law:

F=ma

where

F is the force

m is the mass

a is the acceleration

In this problem, we have:

m = 70 kg is the mass

a=-30 g=-30 (9.8 m/s^2)=-294 m/s^2 is the acceleration (which is negative, because it is a deceleration)

So, we can use the equation above to find the force:

F=(70 kg)(-294 m/s^2)=-20580 N

and the negative sign simply means that the force is in the opposite direction to the motion.

Any two application of gravity
Brrunno [24]

Answer:

Well the definition of an application is the act of putting to a special use or purpose so lam assuming that you want specific uses that scientists make of gravity in their work.

Well our first application has helped us to send satellites around the solar system with what Nasa calls gravity assist. Using a particular planets gravity to slingshot a satellite to another destination. Look it up.

The next application much simpler but here on Earth. There are many hydro-electric power stations in use all over the world. Water is stored at a high level and released falling 100s of metres to a turbine where it generates electricity.

Hope that helps.
