Answer:

3.679 × 10^{8}

Explanation:

Let's assume that average lifespan for normal human being is 70 years.

In 70 years there are 365 days in each year.

70 years = 70 × 365 days

In one day there are 24 hours.

70 years = 70 × 365 × 24 hours

In one hour there are 60 minutes.

70 years = 70 × 365 × 24 × 60 minutes

we estimate an average respiration rate of about 10 breaths per minute. ... (Given)

Thus, for 70 years number of breath are,

n = 70 × 365 × 24 × 60 × 10

n = 3.679 × 10^{8}

Hence, estimate number of breath over a period of life is 3.679 × 10^{8}.

Elan Coil [88]
Momentum is conserved after the collision 

Momentum of 2 Kg before collision = 2 * 3 = 6
Momentum of 4 kg  before collision = 4 * -3 = -12

so 6 + -12 = 2 * -4 + 4 *x   where x is velocity of 4kg marble.

4x - 8 = -6
4x = 2
x = 0.5 

Velocity of 4 kg marble is 0.5 m/s after collision

The 2 kg marble will move in the opposite direction to which it was moving before the collision.

An astronaut on a small planet wishes to measure the local value of g by timing pulses traveling down a wire which has a large o
Alekssandra [29.7K]

Answer:

0.53m/s^2

Explanation:

We are given that

Mass of wire=m=3.6 g=3.6\times 10^{-3} kg

1 kg=1000 g

Length of wire=l=1.6 m

Mass of object=m'=3 kg

Time,t=60.1 ms=60.1\times 10^{-3} s

1 ms=10^{-3} s

Speed,v=\frac{distance}{time}=\frac{1.6}{60.1\times 10^{-3}}=26.62 m/s

g=\frac{v^2m}{m'l}

Using the formula

g=\frac{(26.62)^2\times 3.6\times 10^{-3}}{3\times 1.6}=0.53m/s^2
