<span>Joule was educated at home with private tutors. He had to take over the brewery at a young age and missed out on attending university. Despite this, his home schooling was exceptional and led to him continuing to study science in a home based laboratory where he experimented before and after work. Joule submitted his work on the relationship of heat, electricity and mechanical work to numerous publications but it was widely ignored until William Thomson found it in 1847. He recognized Joule's work worked with an unifying pattern that was newly emerging in physics and excitedly endorsed it. Soon many other big names in the science field began rallying behind Joule's work.</span>

James Prescott Joule, an English scientist, was educated privately by a tutor. From 1834 until 1837, they were taught chemistry, physics, the scientific method, and mathematics by the famous English chemist John Dalton. James recognized or acknowledge the key role that Dalton played in his becoming a scientist. He said: "It was from his instruction that I first formed a desire to increase my knowledge by original researches".

The acceleration of the boat is 2 m/s^2 (eastward)

Explanation:

We can solve this problem by using Newton's second law, which states that:

F = ma (1)

where

F is the net force on a body

m is its mass

a is its acceleration

First of all, we have to find the net force acting on the boat. We have:

- The force of the motor, 100 N eastward

- The force of the air resistance, 60 N westward

So the net force is:

F = 100 N - 60 N = 40 N (eastward)

Now we can apply eq.(1), using:

F = 40 N

m = 20 kg (mass of the boat)

and solving for a, we find the acceleration:

a=\frac{F}{m}=\frac{40}{20}=2.0 m/s^2

And the direction is the same as the net force (eastward).

A light ray incident on a block of glass makes an incident angle of 50.0° with the normal to the surface. The refracted ray in t
Andru [333]

Answer:

n_{glass} = 1.65

Explanation:

As we know that the angle of incidence is given as

i = 50.0^o

also we have angle of refraction as

r = 27.7^o

now by Snell's law we know that

n_{air} sin i = n_{glass} sin r

1 sin50 = n_{glass} sin 27.7

now we have

n_{glass} = \frac{sin 50}{sin 27.7}

n_{glass} = 1.65

What speed should a satellite of mass 4,900 kg moving around
Rudiy27

Based on the calculations, the speed required for this satellite to stay in orbit is equal to 1.8 × 10³ m/s.

<u>Given the following data:</u>

  • Gravitational constant = 6.67 × 10⁻¹¹ m/kg²
  • Mass of Moon = 7.36 × 10²² kg
  • Distance, r = 4.2 × 10⁶ m.

<h3>How to determine the speed of this satellite?</h3>

In order to determine the speed of this satellite to stay in orbit, the centripetal force acting on it must be sufficient to change its direction.

This ultimately implies that, the centripetal force must be equal to the gravitational force as shown below:

Fc = Fg

mv²/r = GmM/r²

<u>Where:</u>

  • m is the mass of the satellite.
  • M is mass of the Moon.

Making v the subject of formula, we have;

v = √(GM/r)

Substituting the given parameters into the formula, we have;

v = √(6.67 × 10⁻¹¹ × 7.36 × 10²²/4.2 × 10⁶)

v = √(1,168,838.095)

v = 1,081.13 m/s.

Speed, v = 1.8 × 10³ m/s.

Based on Archimedes' principle, we know that if an object displaces a given weight of water, then the object is being buoyed up
Virty [35]
True. If the amount displaced is more than the mass, it floats. If the amount is less than the mass, it will sink.
