Potential energy = mass x gravity x height
= 20 x 9.81 x 10
= 1962J

Answer: 1960 Joules

Explanation: Potential energy is the energy possessed by an object by virtue of its position.

P.E=m\times g\times h

P.E = potential energy

m = mass of body = 20 kg

g = acceleration due to gravity =9.8ms^{-2}

h = height of body = 10 m

P.E=20kg\times 9.8ms^{-2}\times 10m=1960kgm^2s^{-2}=1960Joules

(1kgm^2s^{-2}=1Joule)

A cat has a mass of 3 kg and runs at a speed of 6 m/s. how much kinetic energy does the cat have?
RUDIKE [14]
We have: K.E. = 1/2 mv²
Here: m = 3 Kg
v = 6 m/s

Substitute their values, 
K.E. = 1/2 * 3 * 6²
K.E. = 1/2 * 3 * 36
K.E. = 54 J

In short, Your Answer would be 54 Joules

Hope this helps!

How is grounding a positive object different from grounding a negative object?
Natali5045456 [20]

Answer:

Grounding a Positively Charged Object

Electrons were transferred from the electroscope to the ground. As in the case of grounding a negatively charged electroscope, the grounding of a positively charged electroscope involves charge sharing. The excess positive charge is shared between the electroscope and the ground.

Which descriptions apply to Mendels pea plant experiments ? Select three options
const2013 [10]

used cross breeding to purposely breed plan

studied a variety of pea plant traits

studied several generations of plants

In order to breed or cross one plant with another, Mendel opened the petals and removed the anthers from the flower and dusted the pistil with pollen from the plant he wished to cross it with and covered the flower with a small bag to prevent the pollen in the air from landing in the pistil. This process is called cross pollination.

Mendel considered 7 characters of pea plant for his study and did the study for several generations.

Four football players are running down the field at the same speed. Player 1 weighs 180 lbs and is running toward the south goal
Serggg [28]
Player 2 because moment is mass times acceleration and since they are all going the same speed. Speed doesn't matter so the only thing that is left is mass/ weight and he has the most
