Answer:
2.1406 ×
m/sec
Explanation:
we know that energy is always conserved
so from the law of energy conservation

here V is the potential difference
we know that mass of proton = 1.67×
kg
we have given speed =50000m/sec
so potential difference 
now mass of electron =9.11×
so for electron

so the velocity of electron will be 2.1406×
m/sec
Answer:
This is not a question, but a statement. The concept that the work done is equal to the input work on a simple machine is called ideal machine. An ideal machine has 100% efficiency which means that there is no loss. All the amount of input work is equal to the useful output of the machine.
Explanation:
Answer:
The velocity and mass of the target ball are 1.6 m/s and 1.29 kg.
Explanation:
Given that,
Mass of softball = 0.220 kg
Speed = 5.5 m/s
(a). We need to calculate the velocity of the target ball
Using conservation of momentum



....(I)
The velocity approach is equal to the separation of velocity


(b). We need to calculate the mass of the target ball
Now, Put the value of v₂ in equation (I)



Hence, The velocity and mass of the target ball are 1.6 m/s and 1.29 kg.
Temperature increases and molecular motion increases while shape becomes less defined
Answer: translate DNA into RNA <3
Explanation:
An RNA polymerase binds to promoters and then breaks down hydrogen bonds between two strands of the DNA and attaches on one of them. A DNA strand is used as a template for a new RNA molecule. In this way, pre-mRNA is made, which becomes mRNA after the introns are removed.
A mRNA molecule enters the ribosomes, located in the cytoplasm. In these organelles, a transfer RNA attaches to a mRNA and the process of translation begins. The final product is a polypeptide chain.
