Answer: 3,383.5 kg
Explanation:
from the question we were given the following
tension (T) = 4.5 x 10^4 N
maximum acceleration (a) = 3.5 m/s^2
acceleration due to gravity (g) = 9.8 m/s^2 ( it's a constant value )
mass of the car and its contents (m) = ?
we can get the mass of the car and it's contents from the formula for tension which is T = ma + mg
T = m (a + g)
therefore m = T / (a+g)
m = (4.5 x 10^4 / ( 3.5 + 9.8 )
m = 3,383.5 kg
D. the wavelengths that the pigmented object after interacting with sunlight
The frequency of a wave is equal to the linear speed divided the wavelength. so in equation form.
f = v / l
so the wavlength
l = v / f
where f is the frequency
v iss the linear speed
l is the wavelength
l = ( 5100 m/s ) / ( 2.2 Mhz ) ( 10^6 hz / 1 Mhz )
f = 0.0023 m
f = 2.3 mm
I’m pretty sure one increases just straight up velocity and the other is kind of a deceleration
