The new period will be 2.486 days.
<h3>What is the period?</h3>
The period is found as the ratio of the angular displacement and the angular velocity. Its unit is the second and is denoted by t. The value of time needed to complete the rotation is the total period.
Given data;
Mass of a star,m= 1.210×10³¹ kg
The time period for one rotation of the star, T = 20.30 days
D' = 0.350 D
R' = 0.350 R
From the law of conservation of angular momentum;
Hence, the new period will be 2.486 days.

Answer:
The work done will be 57.15 J
Explanation:
Given that,
Mass = 12 kg
Distance = 3 m
Force = 22 N
Angle = 30°
We need to calculate the work done
The work done is defined as,
Where, F = force
d = displacement
Put the value into the formula
Hence, The work done will be 57.15 J
Answer:
test 5 seemed to be the hardest for me to perceive in account i only saw three f's when there was indeed 6 it was very difficult to find the f's even going very slowly.
Explanation:

The chemical formula of a binary molecular compound of hydrogen and a group 7a element that can reasonably be expected to be less acidic in aqueous solution than HBr is HF
Group 7a that forms binary molecular compounds of Hydrogen are Halogens such as Iodine I, Bromine Br, Chlorine Cl and Fluorine F. Out of these four HF is the least acidic. This is calculated based on Acid dissociation constant. HF has the least value out of these four, so it is the least acidic.
A binary molecular compound is a compound that consists of two non metals elements only.
Therefore, the chemical formula of a binary molecular compound of hydrogen and a group 7a element that can reasonably be expected to be less acidic in aqueous solution than HBr is HF.
