M= 130 kg
v= 5 m/s
kinetik energy = ½• m•v²
= ½ • 130• 5²
= ½•130•25
= ½•3250

Answer:
a.
Explanation:
the electrons beams deflection radius will be halved.
Answer:
It will take 9 hours
Explanation:
If a car travels 100 km per hour and 900 km is divided by 100 it will take 9 hours to travel.
Answer:
m = 0.59 kg.
Explanation:
First, we need to find the relation between the frequency and mass on a spring.
The Hooke's law states that
And Newton's Second Law also states that
Combining two equations yields
The term that determines the proportionality between acceleration and position is defined as angular frequency, ω.
And given that ω = 2πf
the relation between frequency and mass becomes
.
Let's apply this to the variables in the question.
