Answer:

Mass of object (m) = 5.102 kg

Explanation:

Given:

Horizontal Force (F) = 50 N

Find:

Mass of object (m) = ?

Computation:

We know that, acceleration due to gravity (g) = 9.8 m/s²

⇒ Horizontal Force (F) = mg

⇒ 50 N = m (9.8 m/s²)

⇒ Mass of object (m) =  50 / 9.8

⇒ Mass of object (m) = 5.102 kg

Mass of object (m) is 5.1 kg (Approx)

Answer: B & D

Explanation:

The objects are moving in opposite directions is the statements accurately describe the motion map, therefore the correct answer is option B

An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.

It is a vector quantity to be displaced. This means that it is visually represented as an arrow that points from the starting position to the ending position and that it has both a direction and a magnitude.

The total distance traveled by an object is different than the total displacement covered by it because the displacement is a vector quantity and it is calculated on the basis of the shortest distance traveled by the body or object.

Thus, The objects are moving in opposite directions is the statements accurately describe the motion map, therefore the correct answer is option B

Explanation:

Frequency is the amount of times the particle moves back and forth per second, more or less. The more energy, the higher the frequency. At the same time, the more energy means you'll have a shorter wavelength (aka period). Color only applies to the visible spectrum.

Answer:

frequency

Explanation: The greater the number of waves appear the greater the energy. The smaller the number of waves appear the lower the energy.

Frequency is the number of times waves appear.

Explanation:

Because the moon has much less mass than the Earth has.  This makes the gravitational forces between the moon and any object much less than the forces between the Earth and the same object, when the object is the same distance from the center of the moon or the Earth.

To talk about an actual number, we usually talk about being on the surface of the Earth or the moon:

A person or object on the surface of the moon weighs about 17% as much as he/it weighs on the surface of Earth. That's about one-sixth as much.  So naturally, it's easier to lift something on the moon than it is to lift the same thing on Earth, because when it's on Earth, it's about six times as heavy.

Answer:

D. 4km/min

Explanation:

Since the question deals with "speed" and not "velocity", the direction does not matter.

the plane covers 40 + 20 km=60km in 10mins +5 mins=15mins

60 km - 15 mins

1min- 60÷15= 4 mins

therefore, your answer is D. 4km/min

The special relativity hypothesis is accepted by all physicists. Even our satellites in orbit must synchronize their clocks and transmissions with those on Earth using Einstein's calculations.

According to special relativity, speed has an impact on space, time, and mass. Small amounts of mass (m) can be interchangeable with vast amounts of energy (E), as indicated by the classic equation E = mc2. This method of defining the link between energy and matter is included in the theory.

Therefore, The relationship between speed, mass, time, and space is described by Einstein's special relativity theory. It describes the equation e=mc2, which asserts that energy is equal to mass times the square of the speed of light.

Answer:

Horizontal distance travelled by the ball.

A. 367m

Explanation:

Projectile motion is a motion in which an object moves in a parabolic path due to the action of gravity on it. Projectile motion only occurs when there is one force which is applied at the beginning, after that the only interference is from gravity. e.g the path of a golf ball after hit by a golfer.

Range of the projectile can be defined as the horizontal distance given by the ball. We need to find Range in this question.

The Range of a projectile is given by:

[tex]R = \frac{v^2\cdot{sin2}\theta}{g}[/tex]

where

v = initial velocity = 25 m/s

θ = 35°

g = 1.6 m/s²

Substitute the values in formula of R:

[tex]R= \frac{(25)^2\cdot{sin(2\cdot35)}}{1.6}\\R= \frac{(625)\cdot{sin(70)}}{1.6}\\R=367m[/tex]

Answer: Average velocity = u+v/2

Explanation: The definition of velocity is displacement over time taken. That is,

Velocity = displacement/ time taken

But we have initial velocity U and final velocity V. When we are talking about average, we are talking about the mean value of the given parameters.

Therefore, average velocity will be addition of initial velocity and final velocity divided by 2. That is,

Average velocity = (U + V)/2

Driving on wide highways frequently results in velocitation and tiredness. The phenomena of accidentally raising speed on roads as a result of repeated exposure to greater speeds is known as velocitation.

It happens when drivers become acclimated to the faster speeds and may unintentionally go over the speed limit, endangering their safety.

Another frequent impact is fatigue, which can occur as a result of extended lengths of repetitive driving on wide-open highways. Fatigue can make it difficult to focus, respond quickly, and make decisions, which makes accidents more likely.

Despite the fact that highway hypnosis and visual effects can also happen when driving, open roads are uniquely linked to velocitation and weariness.

Answer:

50w

Explanation:

Power is equal to Energy divided by Time

∆E/t

Answer:

50 W

Explanation:

Power can be found using the following formula.

p=w/t

where w is work and t is time.

400 Joules of work is done on the object in 8 seconds. Therefore,

w= 400 J

t= 8 s

Substitute these values into the formula.

p=400 J/ 8 s

Divide 400 by 8

p=50 J/s

Add appropriate units. In this case, power uses Watts, or W. (1 Joule per second, or J/s is equal to 1 Watt, or W)

p= 50 W

The object experiences 50 Watts of power
