6 0

Answer:

True

Explanation: Tsunami is a huge displacement of water caused by Earthquakes which took place on inside the sea floor causing extreme flooding and damages to life and tsunami is more prominent in the Pacific Ocean and Indonesia mainly because of the presence of active earthquake zones beneath the ocean. Tsunami has also been observed in the Mediterranean Sea and also in the United States around the year 1933.

If the momentum of a 1000 kg car travelling at 10 m/s was transferred completely to a 20.0 kg traffic barrier, what would the fi
denis-greek [22]

Answer:

d. 500 m/s

Explanation:

Momentum: This is the product of the mass of a body to its velocity, The S.I unit of momentum is kgm/s.

Mathematically, momentum can be expressed as,

M = mv....................... equation 1

Where M = momentum, m = mass, v = velocity

deduced from the question,

Momentum of the car = momentum of the barrier.

MV = mv ............................. Equation 1

Where M = mass of the car, V = velocity of the car, m = mass of the barrier, v = velocity of the barrier.

making v the subject of the equation,

v = MV/m........................ Equation 2

Given: M = 1000 kg, V = 10 m/s, m = 20 kg.

Substitute into equation 2

v = 1000(10)/20

v = 500 m/s.

Hence the speed of the barrier = 500 m/s

The right option is d. 500 m/s

A 12.0-m wire with a mass of 145 g is under tension. A transverse wave, for which the frequency is 630 Hz, the wavelength is 0.5
miskamm [114]

Answer:

The maximum traverse acceleration is   \alpha = 31346.095 m/s^2

Explanation:

Generally the maximum transverse acceleration is mathematically represented as

                   \alpha =  w^2 A

Where w is the angular velocity which is mathematically evaluated as

                 w = 2 \pi f

Substituting the values given in the question

               w = 2 * 3.142 * 630

                   = 3958.92 rad/s

  A is the A is amplitude with a value of 2.0mm = \frac{2}{1000} = 0.002m

         Substituting this into the formula for maximum transverse acceleration

                              \alpha  = 3958.96^2 * 0.002

                                  = 31346.095 m/s^2

if the current in a wire is 2.0 amperes and the potential difference across the wire is 10 volts what is the resistance of the w
Pavlova-9 [17]

Answer:

R = 2Ω

Explanation:

Potential difference (V) = current (I) * Resistance (R)

V = IR

I = 2.0A

V = 10v

R = ?

V = IR

R = V / I

R = 10 / 2

R = 2Ω

The resistance across the wire is 2Ω
