Energy can change form, but the total amount of energy stays the same.
Answer:
The final velocity of the car is 26.65 m/s.
Explanation:
Given;
acceleration of the racecar, a = 6.5 m/s²
initial velocity of the car, u = 0
time of motion, t = 4.1 s
The final velocity of the car is given by;
v = u + at
where;
v is the final velocity of the car
suvstitute the givens
v = 0 + (6.5)(4.1)
v = 26.65 m/s.
Therefore, the final velocity of the car is 26.65 m/s.
Answer:
10.23m/s^2
Explanation:
GIven data
mass of elevator = 2125 kg
Force= 21,750 N
Required
The maximum acceleration upward
F= ma
a= F/m
a=21,750/2125
a= 10.23m/s^2
Hence the acceleration is 10.23m/s^2
Answer and Explanation:
The computation of the shortest wavelength in the series is shown below:-

Where
represents wavelength
R represents Rydberg's constant
represents Final energy states
and
represents initial energy states
Now Substitute is

now we will put the values into the above formula


Now we will rewrite the answer in the term of 

So, the whole Paschen series is in the part of the spectrum.
