Answer :The Momentum of a man riding his bicycle downhill is 400 kg m/s.

Explanation:

Mass of the man of bicycle = 40 kg

Velocity of the bicycle = 10 m/s

Momentum = Mass ×  Velocity = 40 kg × 10 m/s = 400 kg m/s

The Momentum of a man riding his bicycle downhill is 400 kg m/s.

If a volume of air is warmed, it expands and tends to
Butoxors [25]

if a volume of air is warmed it expands due to increased translational kinetic energy as it expands it will start to cool.

<h3>When does temperature increase volume?</h3>

We can then conclude that at constant pressure, temperature and volume are directly proportional: temperature increases, volume increases; decrease temperature, decrease volume.

In this case, the higher the temperature, the greater the kinetic energy that acts on the molecules of this gas, so when the gas expands, these molecules find more space and collide less, which will cause the gas to cool.

A golf ball (mass 0.045 kg) is hit with a club from a tee. The plot shows the force on the ball as a function of time in millise
almond37 [142]

Answer:

16.3 m/s

Explanation:

We are given that

Mass of golf ball=m=0.045 kg

We have to find the speed right after the hit.

b_1=(16-1)\times 10^{-3}=15\times 10^{-3} s

b_2=(12-6)\times 10^{-3}=6\times 10^{-3} s

Force,F=70 N

Change in momentum=Area of trapezium

Area of trapezium,A=\frac{1}{2}(b_1+b_2) h

Using the formula

m(v-u)=\frac{1}{2}(15+6)\times 10^{-3}\times 70

0.045(v-u)=\frac{1}{2}(21)\times 10^{-3}\times 70

v-u=\frac{1}{2}\times \frac{1}{0.045}\times 21\times 10^{-3}\times 70

v-u=16.3

Initial velocity of golf ball=u=0

v-0=16.3

v=16.3 m/s

kirill115 [55]

Healthy pregnant women should get at least 150 minutes of moderate-intensity aerobic activity, spread over a 7-day period, each week - True

<u>Explanation:</u>

Women who are healthy but moderately active must be engaged with aerobic  activities moderately. they should be engaged with this activities at least 2 and a half hours in all 7 days of a week. They must be engaged with this activity during the pregnancy time and also in the period after their delivery.

During the time of pregnancy all women must be healthy and physically active. The ways for maintaining a very good health in the pregnancy time will be guided by the health care providers. Women should be highly active during and after pregnancy time. This helps in having a baby that is also very healthy.
