When you know both the speed and direction of an object’s motion, you know the velocity of an object. speed in a given direction is called velocity
hope this helps :)
Answer:
The correct options are:
1) Protons
Explanation:
Brayons are composite subatomic particles which consist of odd number of valence quarks.Quarks are the fundamental particles in the nature that combine to form other particles such as neutrons and protons. In these composite subatomic particles strong nuclear forces dominate as compared to other fundamental forces in the nature.
A list of brayons includes (names are as represented in theory):
1) Proton's
2) Neutrons
3)Lambda
4) Sigma
5)Xi
6) Omega
7) Delta
Hence we find only proton is matching from the given options.
Electron has the least amount of mass!
Answer:
12010
Explanation:
Given:
power time
4,370 25
4,420 22
4,150 26
To find: difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount
Solution:
Energy = power × time
For clothes dryer x:
energy = 4370 × 25 = 109250
For clothes dryer y:
energy = 4420 × 22 = 97240
For clothes dryer z:
energy = 4150 × 26 = 107900
Dryer x uses the greatest amount of energy and dryer y uses the least amount of energy.
Difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount = 109250 - 97240 = 12010
