Answer:
5.4kgm/s towards the hitter.
Explanation:
Given parameters:
Mass = 0.12kg
Velocity = 45m/s
Unknown:
Momentum of the baseball = ?
Solution:
To solve this problem, we must understand that the momentum of a body is the quantity of motion it possesses.
Momentum = mass x velocity
Now insert the parameters and solve;
Momentum = 0.12 x 45 = 5.4kgm/s towards the hitter.
Answer;
<u>= 56.96 mA</u>
Explanation;
From the Ohm's law;
V = IR, where V is the potential difference in volts, I is the electric current in amperes and R is the resistance in ohms.
V = 4.5 volts, R = 79 Ω
Making I the subject of the formula we get;
I =V/R
= 4.5 /79
= 0.05696 A
But, 1 A = 1000 mA
Thus; 0.05696 × 1000
<u>= 56.96 mA</u>
True, the accepted modern theory of life is biological evolution.
Answer:
A group of protons and neutrons that are surrounded by electrons I think that's the answer...
Explanation:
Number 4 I think
the atomic mass is 11 because the mass is the sum of protons and neutrons
