Describe how earth distance from the sun changes throughout the year when is earth closest to the sun

1 answer:

4 0

The father earth is away from the sun the more cold.
The closer the sun gets the more hot.
When going threw these motions our seasons and days change as the earth moves around the sun while rotating. Hope this helped.

Vesna [10]

Answer:

A. continental-oceanic convergent

Explanation:

I knew it couldn't be B because it's oceanic and continental, not oceanic and oceanic.

Next, I noticed the word convergent, which implies "coming together" to me.

I looked it up and noticed the term convergent referred to a plate boundary where a plate slips under (subducted) another, so I knew it was A.

Hopefully, this helps you understand the question better. Have a great day!

A small object with mass 1.30 kg is mounted on one end of arod

Julli [10]

Answer:

(a) $I_{system} = 1.014\ kg.m^{2}$

(b) $\tau = 0.0179\ N-m$

Solution:

As per the question:

Mass of the object, m = 1.30 kg

Length of the rod, L = 0.780 m

Angular speed, $\omega = 5010\ rev/min$

Now,

(a) To calculate the rotational inertia of the system about the axis of rotation:

Since, the rod is mass less, the moment of inertia of the rotating system and that of the object about the rotation axis will be equal:

$I_{system} = ML^{2} = 1.30\times (0.780)^{2} = 0.791\ kg.m^{2}$

(b) To calculate the applied torque required for the system to rotate at constant speed:

Drag Force, F = $2.30\times 10^{- 2}\ N$

$\tau = FLsin\theta 90 = 2.30\times 10^{- 2}\times 0.780\times 1 = 0.0179\ N-m$

A stone is dropped into a deep well and hits the water after 3.41 seconds. How deep is The well?

TiliK225 [7]

Answer:

57.0 m

Explanation:

Given:

v₀ = 0 m/s

t = 3.41 s

a = 9.8 m/s²

Find: Δx

Δx = v₀ t + ½ at²

Δx = (0 m/s) (3.41 s) + ½ (9.8 m/s²) (3.41 s)²

Δx = 57.0 m

A water skier has a mass of 79.0 kg and accelerates at 1.40 m/s2. What is the net force acting on him? F = ___ N

marysya [2.9K]

The answer is 111.

Using Newton's Second Law, F=ma, plugging known values in we get:

F = (79kg)(1.4m/s^2) = 110.6N ≈ 111N
