"Decimeter" is a unit of length or distance, whereas "milliliter" is
a unit of volume. They measure different quantities, and have
different physical dimensions. Neither one can be converted to
the other one.
If it were possible to convert volume to length or distance, you
(or someone with a better handle on his math and physics) could
figure out how many inches of milk you poured on your cereal.
Answer:
0.0196 Joules
Explanation:
Kinetic energy is half the product of mass and velocity squared.
K.E=0.5 m*v^2; The m is the mass in kilograms and v is the velocity in meters per second.
We will convert grams to kilograms:
2.45 grams = 0.00245 kilograms.
Calculating kinetic energy:
mass:0.00245 kg
velocity:4 m/s
K.E = 0.5 *0.00245*4^2 = 0.0196 Joules.
Answer:
uuuugggghhhhhhhhggggffffffffffffff
Answer:
80 Joules.
Explanation:
Given that a 20 kg sled stars at the top of a hill which is 10 m above the bottom and slides a distance of 50 m, ending at the bottom of the hill with a speed of 8 m/s. During the slide, the work done by gravity is about ?
The parameters given are:
Mass M = 20 kg
Height h = 10 m
Velocity V = 8 m/s
The workdone by gravity will be equal to the total energy
At the bottom of the hill, the total energy will be equal to the maximum kinetic energy.
Maximum K.E = 1/2mv^2
K.E = 1/2 × 20 × 8
K.E = 80J
Therefore, the workdone by the gravity is equal to 80 Joules.
