I only know answer A and it's 2825.28 N/m, with rounding it's 2825.5

Explanation:

Use the m*g*h=1/2*k*x^2 equation

96*9.81*60=1/2*k*2^2

5650.56=2k

5650.56/2=2825.28N/m

nadya68 [22]

Answer:

68 ohm

Explanation:

Output Voltage, Vout = 5 V

Forward voltage, Vf = 3.65 V

Forward current, If = 20 mA = 0.02 A

Let the resistance is R.

Use the formula

$I_{f}=\frac{V_{out}-V_{f}}{R}$

$0.02=\frac{5-3.65}{R}$

R = 67.5 ohm

R = 68 ohm ( approx.)

What is the acceleration of a car that moves at a steady velocity of 100km/h for 100s?

vivado [14]

Answer:

the answer is 0

Explanation:

The acceleration of a car that maintains a constant velocity of 100 km/h for 100s is zero. Acceleration is a change in velocity. Thus, if velocity is constant, that means there is no change and velocity stays the same.
