Answer:
The corona is hotter than the photosphere,
Explanation:
We can calculate it by applying Newton's version of Kepler's third law with Earth's orbital period (1 year) and Earth's average distance from the Sun (1 AU).
Answer:
v_h = 9 m/s
Explanation:
given,
mass of the rocket = 1500 kg
accelerates = 10 m/s²
time = 4 s
one fragment is twice as massive as the other.
maximum height reached by the lighter fragment = 530 m
now,
using equation of motion to calculate the velocity
initial velocity of rocket,u = 0 m/s
v = u + a t
v = at.......(1)
total mass of the rocket
M = m + m'
m' is the heavier particle mass.
m' = 2 m (from the statement given in the question)
M = 3 m
m = M/3
now, again using equation of motion to calculate the initial velocity of the lighter particle.
v² = u² + 2 a s
0² = u² + 2 g h
u = √2gh.....(2)
now,
using conservation of momentum,
2 v_h = 18
v_h = 9 m/s
speed of the heavy fragment is equal to 9 m/s
A type of anchor that is a good choice when jacking or leveling the fastening component is a stud bolt anchor.
<h3>What is a Stud bolt anchor?</h3>
These are the type of anchor which bare embedded in concrete with the threaded portion on the outside.
This makes it easier to jack or level the fastening component which is why option B was chosen.

Answer:
- it turns electrical signals into radio waves so they can travel sometimes thousands of kilometers around the Earth or even into space and back.
Explanation:
In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as radio waves. I HOPE THIS HELPS:)
