Suppose that we replace the aluminum with a mystery metal and repeat the experiment in the video. As in the video, the mass of the metal is the same as that of the water. Room temperature is about 20∘C before the start of the experiment. The water heats up to 40∘C, and the mystery metal heats up to 80∘C. Compared to that of water, the heat capacity of our mystery metal is

Answers

Answer 1

Answer: b) one-third as great.

Explanation:

The options include:

a) three times greater.

b) one-third as great.

c) half as great.

d) two times greater.

e) the same.

Since the water heats up to 40°C and the room temperature is about 20°C before the start of the experiment, heat absorbed will be: (40°C-20°C).= 20°C

Since mystery metal heats up to 80∘C and the room temperature is about 20°C before the start of the experiment, heat absorbed will be: (80°C-20°C).= 60°C.

Therefore, based on the calculation, when compared to that of water, the heat capacity of our mystery metal is (20/60) = 1/3 one-third as great.

A lens 57.8 cm from an object
forms an image 38.5 cm from the
lens. What is the focal length of
the lens?

Answers

Answer:

23.11

Explanation:

accellus

The focal length of the lens is approximately 115.3 cm. The explaination is  explained below.

To find the focal length of the lens, we can use the lens formula:

1/f = 1/v - 1/u

Where:

f is the focal length of the lens

v is the distance of the image from the lens

u is the distance of the object from the lens

Given:

v = 38.5 cm

u = 57.8 cm

Let's substitute these values into the formula:

1/f = 1/38.5 - 1/57.8

Now, let's calculate the right side of the equation:

1/f = (57.8 - 38.5) / (38.5 * 57.8)

= 19.3 / (2223.3)

≈ 0.008677

Now, we can find the focal length (f) by taking the reciprocal of both sides:

f = 1 / (0.008677)

≈ 115.3 cm

Therefore, the focal length of the lens is approximately 115.3 cm.

В.36.3 newtons
C. .63.5 newtons
D. 95.5 newtons

Answers

Split F₁ into its horizontal and vertical components:

F₁ = F₁ cos(θ) i + F₁ sin(θ) j

(boldface = vector; regular font = magnitude)

By Newton's second law, if the object is in equilibrium, then

• the net horizontal force on the block is

F = F₁ cos(θ) - F₃ = 0   →   F₁ cos(θ) = 70 N

• the net vertical force is

F = F₁ sin(θ) + F₂ - W = 0   →   F₁ sin(θ) = 65 N

Recall that cos²(θ) + sin²(θ) = 1 for any θ, so we have

(F₁ cos(θ))² + (F₁ sin(θ))² = (70 N)² + (65 N)²

F₁² = 9125 N²

F₁ = √(9125 N²) ≈ 95.5 N

Answer:

Law 2:

Pushing a baby on a swing is easier than pushing an adult on the same swing. Water spills from a glass carried by someone who is walking steadily and suddenly stops short.

Law 2:

When thrown with the same force, a soccer ball accelerates more than a bowling ball.

Law 1:

A magician pulls a tablecloth out from under a dish on a table without disturbing the dish.

Law 3:

A rocket launches into space, pushing fuel exhaust in one direction and the rocket in the opposite direction.

Law 1:

A book rests on top of a shelf and does not move until a student accidentally knocks it off.

Explanation:

Newton's laws of motion:

Law 1: Law of inertia

Law 2: Law of force (F = mass x acceleration)

Law 3: Law of Action & Reaction

The laws followed by the given situations are Newton's law of force, Law of inertia and Newton's third law.

What is meant by inertia ?

Inertia is defined as the tendency of an object to continue its state of rest or motion.

Here,

Considering the situations given,

1. Pushing a baby on a swing is easier than pushing an adult on the same swing.

This is because, the mass of the baby is lesser than that of the adult. So, according to Newton's force equation,

Force, F = ma

Therefore to push a body with more mass, more force should be applied.

Another situation that follows this law from the given situations is:

When thrown with the same force, a soccer ball accelerates more than a bowling ball.

2. Water spills from a glass carried by someone who is walking steadily and suddenly stops short.

This is due to the inertia of the water in the glass. This can be explained by law of inertia.

Another situation that follows this law from the given situations is:

A magician pulls a tablecloth out from under a dish on a table without disturbing the dish.

A book rests on top of a shelf and does not move until a student accidentally knocks it off.

3. A rocket launches into space, pushing fuel exhaust in one direction and the rocket in the opposite direction.

This is according to Newton's third law of motion. The law of action and reaction.

Hence,

The laws followed by the given situations are Newton's law of force, Law of inertia and Newton's third law.

The distance between the two nearest points on a wave where the particles are in phase is 2 m. What is the wavelength of the wave?

A. 1/2 m

B. 1 m

C. 2 m

D. 2 seconds

E. none of these

Answers

Answer:

Suppose that the wave equation is:

f(x) = A*cos(k*x)

The wave is in phase for two points x₁ and x₂ if:

f(x₁) = f(x₂)

And if these points are consecutive (for example, two consecutive peaks) then the wavelength of the wave is:

wavelength = x₂ - x₁

In this case, we know that the wave is in phase for two points that are 2 m apart.

Then we can use the points:

x₁ and x₂ such that:

x₂ = x₁ + 2m

We also know that these are the nearest points such that this happens, then we can assume that the points are consecutive.

Then the wavelength will be:

wavelength = x₂ - x₁ = (x₁ + 2m) - (x₁) = 2m

Then the wavelength is 2m.

The correct option is C.
