Answer:
T = mg - 
×V×g
Explanation:
Here we have the mass of the ball is given as 
The density of the fluid =
The volume of the ball = V
Acceleration due to gravity = g
According to Archimedes's principle, the upthrust = Weight of fluid displaced
Tension in string = T = weight of ball - upthrust
T = mg - ×V×g
Answer:
B
Explanation:
a straight yellow is a no pass zone
Where you get all the steps when you finally get a reaction . Ex, vinegar and baking soda you go step by step.
Hope this helps :)
294000J
Explanation:
Given parameters:
Height of hill = 500m
Mass of Chris = 60kg
Unknown:
Potential energy increase = ?
Solution:
Potential energy is the energy by virtue of the position of a body.
Potential energy = mgh
m is the mass of the bike
g is the acceleration due to gravity
h is the height
At the base of the hill,
P.E = mgh = 60 x 9.8 x 0 = 0J
At the top:
P.E = mgh = 60 x 9.8 x 500 = 294000J
Potential energy increase = 294000J - 0J = 294000J
