Answer: 9kgm/s
Explanation:
Given that,
Mass of ball = 3 kg
Speed by which ball moves = 3 m/s. Linear momentum of the ball = ?
Since momentum refers to the quantity of motion of the moving ball,
Linear momentum = Mass x Speed
= 3kg x 3m/s
= 9 kgm/s
Thus, the linear momentum of the ball is 9kgm/s

I know It cause i took that test last year. Just wanna help GL.
Answer:41.991ml
Explanation:
Equations: 2 H2O → 4H+ + 4e + O2 OXIDATION
2 H+ + 2e → H2 REDUCTION
Electrolysis is the chemical decomposition of compounds when electricity is made to pass through a molten compound or solution.
from the oxidation reaction:
1moles of oxygen requires 4moles of electrons to be discharged at the product
F=96500C/mol
Quantity of charge Q=It
=60*60*0.201A
Q=723.6C
Mole=Q/(F*mole ratio of electron)
Mole= 723.6/(4*96500)
Mole=((1809)/(965000))
M=0.0018746114
M1/M2=V1/V2
1/0.00187=22.4dm^3/V2
V2=22.4*0.00187
V2=0.04199129534dm^3
41.99129534ml
Answer:
Different forces (including magnetism, gravity, and friction) can affect motion
Answer:
A and B
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Thus, the product of the wavelength and the frequency is constant and equal to
<u>Option A is correct.</u>
Given, Frequency = 
Thus, Wavelength is:
Also, 1 m = 
Å
So,
<u>Wavelength = 3.0 Å</u>
<u>Option B is correct.</u>
As stated above, the speed of electromagnetic radiation is constant. Hence, each radiation of the spectrum travels with same speed.
<u>Option C is incorrect.</u>
