Answer:
so two people can understand each other when presenting new ideas to each other
Explanation:
Answer:
A) G = m³/kg.s²
B) E = kg.m²/s²
Explanation:
A)
The given relation is:
F = Gm₁m₂/r²
where, the units of all variables are:
F = Force = kg.m/s²
m₁ = m₂ = mass = kg
r = distance = m
G = Gravitational Constant = ?
Therefore,
kg.m/s² = G(kg)(kg)/m²
(kg.m/s²)(m²/kg²) = G
<u>G = m³/kg.s²</u>
<u></u>
B)
The given equation is:
E = mc²
where, the units of all variables are:
m = mass = kg
c = speed = m/s
E = Energy = ?
Therefore,
E = (kg)(m/s)²
<u>E = kg.m²/s²</u>
This is the correct answer, which is not present in any option.
A: The positive charge if the protons in the nucleus equals the negative charge in the electron cloud.
Protons are positive, electrons are negative, and neutrons have no charge/are neutral
The given question is incomplete. The complete question is:
Estimate the volume of each ball. Use the formula
where v is the volume and r is the radius. record the volume in table A of your student guide. The radius of the tennis ball is 2.1 cm and the radius of thr golf ball is 2.0 cm. What is the estimated volume of the table tennis ball in
What is the estimated volume of the golf ball in
Answer: Volume of the tennis ball is
and Volume of the golf ball is 
Explanation:
We have to find the Volume of tennis ball and golf ball by using the formula 
Radius of the tennis ball = 2.1 cm
Radius of the golf ball =2.0 cm.
Putting the value of radius in the formula , we get:
Volume of the tennis ball = 
Volume of the golf ball = 
Volume of the tennis ball is
and Volume of the golf ball is
