Mechanical waves

Explanation:

Mechanical waves transfers energy from one place to another in a medium by the disturbance of particles of such medium.

Electromagnetic waves are waves resulting from the vibration of electrical and magnetic fields.

To have knocked down a glass, mechanical waves would be best. They would have caused the disturbance of the air particles around, transmit energy and distort the resting glass.

Electromagnetic waves are primarily radiations and do not require a medium. They could not have not have knocked over the glass.

Answer:

$F_f=7.0035\times 10^{-7}\ N$

$F_j=8.45\times 10^{-6}\ N$

Explanation:

(a)

mass of baby, $m_b=4.2\ kg$

mass of father, $m_f=100\ kg$

distance between father and baby, $d=0.2\ m$

<u>Now, the gravitational force on baby due to father:</u>

$F_f=G \frac{m_b.m_f}{d^2}$

$F_f=6.67\times 10^{-11}\times \frac{4.2\times 100}{0.2^2}$

$F_f=7.0035\times 10^{-7}\ N$

(b)

distance between baby and Jupiter, $r=6.29\times 10^{11}\ m$

We have mass of Jupiter, $m_j=1.898\times 10^{27}\ kg$

<u>Now, the gravitational force on baby due to planet Jupiter:</u>

$F_j=G \frac{m_b.m_j}{r^2}$

$F_j=6.67\times 10^{-11}\times \frac{4.2\times 1.898\times 10^{27}}{(6.29\times 10^{11})^2}$

$F_j=8.45\times 10^{-6}\ N$

We find that the gravitational force due to Jupiter is considerably greater than the force due to mass of father.

It is 4.0 km from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/h

Musya8 [376]

Answer:

Explanation:

To solve this problem we have to take into account that the energy consumed per second is the power. Hence, by multipling the power and the time spent to arrive to the lab we obtain the total energy consumed.

But first we have to calculate the time

$t_{1}=\frac{x}{v_{1}}=\frac{4km}{10\frac{km}{h}}=0.4h=0.4(3600s)=1440s\\t_{2}=\frac{x}{v_{2}}=\frac{4km}{3\frac{km}{h}}=1.3h=1.3(3600s)=4800s\\$

Now we use E=W*t for both times

$E_{1}=t_{1}W_{1}=(1440s)(700W)=1008000J\\E_{2}=t_{2}W_{2}=(4800s)(290W)=1392000J\\$

A. Hence, by running the energy consumed is lower.

E1=1008000J

E2=1392000J

C. Because the more intense exercise is made in a lower time in comparison with the less intense exercise, and higher the time, more energy is consumed.
