I hope you fall down a 40 floor hotel resort onto the porch, and explode into the gushing body you are!
Explanation:
First bacterial cells are usually much smaller than plant or animal cells. a human skin cells , for example is about times as larger as an average bacterial cell.
Answer:
Explanation:
Given
Force exerted by machine 
Weight of Block 
Considering inclination to be 
After resolving Forces We get
Answer: K.E = 8.3 J
Explanation:
The given parameters are
Height h = 169.2 m
Mass m = 0.005kg
From conservation of energy, at the top of the monument, the total energy will be kinetic energy which is equal to the potential energy. That is,
K.E = P.E
And
P.E = mgh
Where g = 9.81 m/s^2
Substitutes all the parameters into the formula
P.E = 0.005 × 9.81 × 169.2
P.E = 8.2908 J
Therefore, the kinetic energy (KE) of the nickel in her shirt pocket at the top of the monument is approximately 8.3 Joule.
Answer:C
Explanation:
let the speed be v for both mass x and mass y
mass(x)=500kg
mass(y)=2000kg
Kinetic energy(mass(x))=(500 x v^2)/2
Kinetic energy(mass(x))=250v^2
Kinetic energy(mass(y))=(2000xv^2)/2
Kinetic energy(mass(y))=1000v^2
Ratio of kinetic energy y to x =1000v^2:250v^2
=1000v^2 / 250v^2
=4/1=4:1
