Someone help I'm stuck on question 8 and 12

Describe You toss a ball to someone one meter away. Then you toss it to someone four meters away. How does your throw change?

krek1111 [17]

We have that the Throw has changed in distance the ball has traveled and the Force applied in trowing the ball and Possibly the time of travel

From the Question we are told that

You toss a ball to someone one meter away

You toss it to someone four meters away

Generally

When you toss toss a ball to someone one meter away and You toss it to someone four meters away the are things that have changed

Force
Distance

Therefore

The Throw has changed in distance the ball has traveled and the Force applied in trowing the ball and Possibly the time of travel

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

The current in a light bulb is 0.835A.How long does it take for a total charge of 1.67 C to pass a point in the wire

adelina 88 [10]

2s

Explanation:

Given parameters:

Current = 0.835A

Quantity of charge = 1.67C

Unknown:

Time taken = ?

Solution:

The quantity of electricity Q in coulombs is the product of the current I and time t.

Q = I x t

Q is the quantity of electricity in coulombs

I is the current

t is the time taken

input the values and solve for t;

1.67 = 0.835 x t

t = $\frac{1.67}{0.835}$ = 2s

The speed of a sound wave in seawater is

9966 [12]

I think some of the given is wrong, 10 ms-1, think it is only 10 s-1 which represents the frequency of the wave, and can be use to solve for the wavelength of the sound wave given
wavelength = wave speed / frequency
wavelength = 1500 m/s / 10 s-1
wavelength = 150 m ( 100 cm / 1 m ) = 15000 cm
