Can you please answers these for me please today is the last day to turn in work and I need this to pass please I’m begging than

Ymorist [56]

Answer:

1. F = ma F = 0.2kg * 20m/s² = 4Kg * m/s² = 4N

2. F = ma F - 18Kg * 3m/s² = 54Kg * m/s² = 54N

3. F = ma F = 0.025Kg * 5m/s² = 0.125N

4. F = ma F = 50Kg * 4m/s² = 200N

5. F = ma F = 70Kg * 4m/s² = 280N

6. F = ma F = 9Kg * 9.8m/s² = 88.2N

What is the wavelenght of an earthquake wave if it has a speed of 11 km/s and a frequency of 15 Hz

Zolol [24]

Answer:

The wavelength is about 733 meters.

Explanation:

Use the wavelength-frequency relationship:

$\lambda = \frac{v}{f}= \frac{11000 \frac{m}{s}}{15 s^{-1}}\approx733m$

The wavelength is about 733 meters.

Options: A.) 10 N B.) 15 N C.) 25 N D.) 35N

Lady_Fox [76]

Given:

F_gravity = 10 N

F_tension = 25 N

Let's find the net centripetal force exterted on the ball.

Apply the formula:

$\sum ^{}_{}F_{\text{net}}=F_1+F_2=F_{centripetal}$

From the given figure, the force acting towards the circular path will be positive, while the force which points directly away from the center is negative.

Hence, the tensional force is positive while the gravitational force is negative.

Thus, we have:

$F_{\text{net}}=F_{\text{centripetal}}=F_{tension}-F_{gravity}=25N-10N=15N$

Therefore, the net centripetal force exterted on the ball is 15 N.

ANSWER:

15 N
