Anettt [7]

Answer:

The speed of the automobile after 1.43s is 10 \frac{m}{s}

Explanation:

a= \frac{-f}{m}= \frac{-u_{k}*m*g}{m}

a= -u_{k}*g=- 0.590* 9.8 \frac{m}{s^{2} }= -5.782 \frac{m}{s^{2} }

V_{f} = V_{i} + a*t

V_{f} = 18.2 \frac{m}{s} - (5.782 \frac{m}{s^{2} }* 1.43 s)

V_{f} = 9.93174 \frac{m}{s}

V_{f} ≅ 10 \frac{m}{s}

The magnitude of the Normal Force on a
lbvjy [14]

Answer:

5. Is greater than mg, always

Explanation:

If the cone has an inclination of angle β, the sum of forces will be:

x-axis (centripetal axis):

N*sin β = m*ax  where ax is the centripetal acceleration

y-axis:

N*cos β - m*g = m*ay   where ay is the vertical acceleration. If the block starts falling down, ay will be negative. If the block starts sliding up, ay will be positive. If the block does not move up nor down, ay=0.

Solving for N:

N = \frac{m*g + m*ay}{cos \beta }

If ay is positive or zero, N will be greater than mg. If ay is negative, N will be less than mg.

If the block is sliding along a horizontal circular path (not up, nor down), ay = 0, so N will always be greater than mg.

A scientist is studying a shock wave from an earthquake. What kind of wave is being studied? an electromagnetic wave a gamma ray
Anettt [7]
<span>So we want to know what kind of wave is the scientist is studying while studying earthquakes. Waves that produce earthquakes are mechanical waves. Gamma rays and radiowaves are both electromagnetic waves and don't require a medium but mechanical do. So the correct answer is mechanical waves.</span>
