Calculate the momentum pelephant of a 2140 kg elephant charging a hunter at a speed of 7.63 m/s . pelephant= kg⋅m/s Compare the

elephant's momentum with the momentum pdart of a 0.0415 kg tranquilizer dart fired at a speed of 619 m/s . pelephant=pdart pelephant>pdart More information is needed to determine how the momentums compare. pelephant

Answer:

Momentum of elephant is greater than momentum of tranquilizer dart

Explanation:

m_e = Mass of elephant = 2140 kg

m_d = Mass of tranquilizer dart = 0.0415 kg

v_e = Velocity of elephant = 7.63 m/s

v_e = Velocity of tranquilizer dart = 619 m/s

Momentum of elephant

p_e=m_ev_e\\\Rightarrow p_e=2140\times 7.63\\\Rightarrow p_e=16328.2\ N.s

Momentum of tranquilizer dart

p_d=m_dv_d\\\Rightarrow p_d=0.0415\times 619\\\Rightarrow p_d=25.6885\ N.s

So, p_e>p_d

Momentum of elephant is greater than momentum of tranquilizer dart

A radioactive material has a count rate of 400 per minute. It has a half life of 40 years. How long will it take to decay to a r
cestrela7 [59]

Answer:

160 years.

Explanation:

From the question given above, the following data were obtained:

Initial count rate (Cᵢ) = 400 count/min

Half-life (t½) = 40 years

Final count rate (Cբ) = 25 count/min

Time (t) =?

Next, we shall determine the number of half-lives that has elapse. This can be obtained as follow:

Initial count rate (Cᵢ) = 400 count/min

Final count rate (Cբ) = 25 count/min

Number of half-lives (n) =?

Cբ = 1/2ⁿ × Cᵢ

25 = 1/2ⁿ × 400

Cross multiply

25 × 2ⁿ = 400

Divide both side by 25

2ⁿ = 400/25

2ⁿ = 16

Express 16 in index form with 2 as the base

2ⁿ = 2⁴

n = 4

Thus, 4 half-lives has elapsed.

Finally, we shall determine the time taken for the radioactive material to decay to the rate of 25 counts per minute. This can be obtained as follow:

Half-life (t½) = 40 years

Number of half-lives (n) = 4

Time (t) =?

n = t / t½

4 = t / 40

Cross multiply

t = 4 × 40

t = 160 years.

Thus, it will take 160 years for the radioactive material to decay to the rate of 25 counts per minute.
