A photo frame with a mass of 2.8 kg is hung from a nail according to the opposite figure. If we know that the nail is located exactly in the middle of the string and the frame does not touch the wall, how many newton is the tensile strength of the string?

Answer:

D) 100 kilometres/hour.

Explanation :

Given -

To find -

Solution -

★ Velocity = displacement/time

→ V = 200/2

→ v = 100 km/h

Therefore, the average velocity of the car is 100 km/h.

Answer:

Atoms: They are the smallest part of matter that may or may not exist independently. When atoms come together they form molecules.

Molecules: Many atoms combined either chemically or naturally form molecules. They are the smallest unit of matter that exist independently.

Answer:

Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides.

Explanation:

Answer:

Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin. Waves are most commonly caused by wind.

Explanation:

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question

m = 80 g = 0.08 kg

v = 15 m/s

We have

[tex]KE = \frac{1}{2} \times 0.08 \times {15}^{2} \\ = 0.04 \times 225[/tex]

We have the final answer as

Answer:

10.21m/s²

Explanation:

Radial acceleration, also known as centripetal acceleration, refers to the acceleration of an object along the circular radius. It can be calculated using the formula:

a(r) = v²/r

Where a(r) = radial acceleration

v = velocity

r = radius of the circular path

According to the information provided in the question, velocity (v) = 17.5m/s, radius = 30m. Hence;

a(r) = v²/r

a(r) = 17.5²/30

a(r) = 10.208333

a(r) = 10.21m/s²

Answer:

y = 15.61 [m]

Explanation:

To solve this problem we must use the following kinematics equation. We must bear in mind that the acceleration of gravity is negative since the direction of gravity is opposite to the direction of motion.

[tex]v_{f} ^{2} = v_{i} ^{2} -(2*g*y)[/tex]

where:

Vf = final velocity = 0

Vi = initial velocity = 17.5 [m/s]

g = gravity acceleration = 9.81 [m/s^2]

y = height [m]

The final speed is zero, since the ball reaches the maximum height its speed will be zero since it cannot be lifted up more.

0 = (17.5)^2 - (2*9.81*y)

306.25 = 2*9.81*y

y = 15.61 [m]

Answer:

A. Atoms of the same element but ith different mass.

Explanation:

Answer: Isotopes are  Atoms of the same element but with different mass

Explanation: Atoms of the same element but with different mass

Answer:

The acceleration is a = 2.75 [m/s^2]

Explanation:

In order to solve this problem we must use kinematics equations.

[tex]v_{f} = v_{i} + a*t\\[/tex]

where:

Vf = final velocity = 13 [m/s]

Vi = initial velocity = 2 [m/s]

a = acceleration [m/s^2]

t = time = 4 [s]

Now replacing:

13 = 2 + (4*a)

(13 - 2) = 4*a

a = 2.75 [m/s^2]

Answer:

50 s

Explanation:

Given:

Δx = 0.005 m

v₀ = 0 m/s

t = 0.50 s

Find: a

Δx = v₀ t + ½ at²

0.005 m = (0 m/s) (0.50 s) + ½ a (0.50 s)²

a = 0.04 m/s²

Given:

Δx = 50 m

v₀ = 0 m/s

a = 0.04 m/s²

Find: t

Δx = v₀ t + ½ at²

50 m = (0 m/s) t + ½ (0.04 m/s²) t²

t = 50 s

Answer:direction

Explanation:

A vector must always have both sizes as well as direction, while on the other hand, any scalar quantity such as the mass of an object would only have magnitude but not direction.

The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.

Examples of vector quantities are displacement, velocity acceleration, force, etc.

A scalar number, such as an object's mass, would only have magnitude but not direction, unlike a vector, which must always have both quantities and direction.

Answer:Explanation:

If the same strength force is exerted on two objects, but the objects have the different masses, the object with less mass will have a greater change in velocity. ... Forces affect motion because they can change an objects motion.

The reason for two objects being impacted differently even a similar strength of the force is applied/exerted to them:

- Two objects might be affected differently on the application of a force of the same strength owing to the difference in their masses.

Answer:

C

Explanation:

Potential energy is energy that something has when its not moving. Kinetic energy is energy in motion. A ball held over a persons head isn't moving, meanwhile a ball in motion is using kinetic energy.

C)A ball held over a person's head | a ball rolling on the floor.

Objects may have each kinetic electricity and capacity electricity at an equal time. An item may be accelerated above the ground (have capacity electricity) and be shifting at the identical time (and now have kinetic electricity). A baseball, a plane, and a flying chicken are all easy examples of this.

A rushing bullet, a walking person, and electromagnetic radiation like mild all have kinetic energy. Some other example of kinetic strength is the strength associated with the constant, random bouncing of atoms or molecules.
