Answer: I believe that it is A and D. Or A or D.
A, D
Explanation:
Answer:
1.3889 x 10¹¹ miles.
Explanation:
2 Years = 2 x 365 days = 730 days
2 years and 9 days = 739 days .
739 days = 739 x 24 = 17736 hours
2 years 9 days and 4.5 hours = 17736 + 4.5 = 17740.5 hours
17740.5 hours = 17740.5 x 60 x 60 = 63.865 x 10⁶ s
Distance travelled = velocity x time
2174.799173 x 63.865 x 10⁶ = 1.3889 x 10¹¹ miles.
Answer:
A. Known variables include
Wavelength = 600nm
Theta= 65°
m= 2
B.
d= m x wavelength / sin theta
= 2 * 600*10^-9 /sin 65°
= 1.3*10^-6m
C.
N = 1/d
So N = 1/1.3*10^-6m
=76.9 lines per micro meter
Kinetic energy of the ball is (mv²) / 2, where m is the mass and v is the velocity
So plugging in the mass and the velocity into the kinetic energy expression, you get:
Kinetic energy of the ball = (mv²) / 2
(0.3125/32) times (132)² divided by 2 = 85 ft-lbs
Kinetic energy of the ball = 85 ft-lbs
Answer:
spring deflection is x = (v2 / R + g) m / 4
Explanation:
We will solve this problem with Newton's second law. Let's analyze the situation the car goes down a road and finds a dip (hollow) that we will assume that it has a circular shape in the lower part has the car weight, elastic force and a centripetal acceleration
Let's write the equations on the Y axis of this description
Fe - W = m 
Where Fe is elastic force, W the weight and
the centripetal acceleration. The elastic force equation is
Fe = - k x
4 (k x) - mg = m v² / R
The four is because there are four springs, R is theradio of dip
We can calculate the deflection (x) of the springs
x = (m v2 / R + mg) / 4
x = (v2 / R + g) m / 4
