a temperature difference and the presence of electromagnetic waves

Explanation:

For radiations to occur, there must be presence of temperature difference and electromagnetic waves.

Radiation is a form of heat transfer that does not require a medium. Any hot body emits radiation from its surface.

A hot body is not at thermal equilibrium with its environment.

It has some of its electrons in excited state and by so they emit radiations.

Electromagnetic waves that vibrates transversely emits radiations. This is the mode of heat transfer in place for most electromagnetic waves

a train engineer started the train from a standstill and sped up to 5 meters per second, she then rounded a corner at a constant
olasank [31]

for acceleration we can define that rate of change in velocity is know as acceleration

So whenever velocity of train is changing with time we can say train is accelerating

Now here if initially train is standstill then after some time its speed is 5 m/s

so here the train is accelerated first time

Then on straight path its speed changed from 5 m/s to 10 m/s so here train gets accelerated second time

After this train chugged around a curve with same speed 10 m/s

SO here since train is moving in curve so here its direction of velocity is continuously changing and this type of acceleration is known as centripetal acceleration

SO this is accelerated Third time

Then its speed decreases and it comes to speed of 5 m/s from 10 m/s

So here it is acceleration of train for Fourth time

Then finally train comes to stop so again its speed changed from 5 m/s to 0

so this is acceleration of train Fifth time

So total train will accelerate 5 times in whole path

Compare the acceleration of a small car and a large truck if an equal force is applied to each vehicle.
tia_tia [17]

Answer:

Acceleration of truck is smaller as compared to the car

Explanation:

We can use newtons second law to solve this

Net Force = mass × acceleration

With the sane force applied and a larger mass of truck, acceleration of truck would be smaller as compared to the car

David’s pulse is 80 beats per minute what is the frequency of his pulse in beats per second and how long does it take between he
Alexxandr [17]

Answer:

1.333 beats/s

It takes 0,755 s per beat

Explanation:

If we want to convert this frequency from beats per minute to beats per second, we have to do the following:

80\frac{beats}{min} \frac{1min}{60s}=1.333\frac{beats}{s}

This means that in 1 second David has 1.333 heart beats.

Now, if we want to know how long does it take between heart beats, we can use the mathematical<u> Rule of Three</u>:

1.333 beats ---- 1s

1 beat ------ ?

?=\frac{(1 beat)(1s)}{1.333 beats}

?=0.75 s This means there are 0.75 s between heart beats
