Hiiii guyssss please help meeee :)

Answer:

XXXTENTACION or Juice WRLD?

Explanation:

Answer:

B: It is moving north.

Explanation:

We are told that a train is moving with a velocity of 70 km/h.

Now, we are also told that the positive direction is north.

This means that the train is moving in the northern direction.

We can't say if it is speeding up or not because we are not given the acceleration.

Thus, option B is correct

Answer:

It is moving north.

Explanation:

I took the test.

Answer:

29.4 J

Explanation:

PE= MGH

PE = 1.5 x 2x 9.8

Answer:

Knee Pads (D)

Explanation:

Considering that Knee Pads are an optional piece of equipment in soccer (but are mostly used by goalies) and that soccer players generally don't wear them I would say that it's D

Wave A has a lower frequency than Wave B.

Explanation:

Frequency is the number of waves passing through the unit time.

As the statement of the question says that the coils in wave A are widely and tightly spaced.

While in wave B the coils are widely and very tightly spaced which means the number of coils is more and the frequency of wave B is more than wave A.

Therefore more coils will pass through a fixed point in unite time and more will be the frequency.

Answer:

the velocity of the car is 30 m/s.

Explanation:

Given;

Centripetal force on the car, F = 900 N

mass of the car, m = 10 kg

diameter of the circular path, d = 20 m

radius of the circular path, r = 10 m

The velocity of the car is calculated as follows;

[tex]F = \frac{mv^2}{r} \\\\mv^2 = Fr\\\\v^2 = \frac{Fr}{m} \\\\v = \sqrt{\frac{900 \times 10}{10} } \\\\v = 30 \ m/s[/tex]

Therefore, the velocity of the car is 30 m/s.

Answer:

According to the Conservation of Momentum,

Momentum of the gun = momentum of the bullet

M(gun)×V(gun)=m(bullet)×v(bullet)

4kg × V = 0.3kg × 600m/s²

V = (0.3 × 600)/4 = 45 m/s

The recoil velocity on the gun is 45 m/s

Answer:

Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.

Answer: straight

Explanation:

If an object moves at a constant speed, the line on a distance/time graph would be straight.

Since the object is moving at a speed which is constant, it'll have a straight line because the direction of the object is not changed.

Answer:

Time = 600 seconds

Explanation:

Given the following data;

Power = 60W

Energy = 36000

To find the time;

Energy = power * time

Substituting into the equation, we have;

36000 = 60 * time

Time = 36000/60

Time = 600 seconds.

Therefore, the bulb was on for 600 seconds.

Answer:

20 ms¯¹

Explanation:

3. Determination of the final velocity

From the question given above, the following data were obtained:

Time (t) = 4 s

Acceleration (a) = 5 ms¯²

Initial velocity (u) = 0 ms¯¹

Final velocity (v) =?

Acceleration is simply defined as the change in velocity per unit time.

Mathematically, it can be expressed as:

Acceleration (a) = final velocity – Initial velocity / time

a = v – u / t

With the above formula, we can obtain the final velocity of the car as follow:

Time (t) = 4 s

Acceleration (a) = 5 ms¯²

Initial velocity (u) = 0 ms¯¹

Final velocity (v) =?

a = v – u / t

5 = v – 0 / 4

5 = v / 4

Cross multiply

v = 5 × 4

v = 20 ms¯¹

Thus, the final velocity of the car is 20 ms¯¹

Answer:

88N

Explanation:

m = 9kg

a = 9.8m/s²

F = ma = 9 × 9.8

F = 88N

Answer:

Newtons first law states that:

If a body is in rest or motion in a straight line, it remains at rest or at motion in a straight line with constant speed until and unless and external unbalanced force acts on it.

'This law is also known as the law of Inertia.'

Explanation:

In this question, it is usually designing the question with difference calculus but instead demonstrate there is an empirical term for both the answer of a nonlinear equation is the decay, Throughout the preliminary training programs, the origin of a damping word is usually resistance or Rossiter.

Distance divided by time is known as the speed of the given body or the object the result we get out by dividing the distance from the time is a scalar quantity as it does not depend on the direction of the moving object.

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.

Let us suppose an ant is moving and it covers a total distance of 2.5 meters in 25 seconds, then if we divide the time taken by the ant by the distance traveled by the ant we would get the speed of the ant.

Thus, distance divided by time is known as speed.

#SPJ6

Answer:

You can make an electromagnet stronger by doing these things: wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil. increasing the current flowing through the coil.

Explanation:

Answer:

162

Explanation:

Answer:

See the explanation below.

Explanation:

At the highest point is where potential energy is maximum and kinetic energy is zero.

Because potential energy is defined as the product of mass by gravitational acceleration by height, this is expressed within the following equation:

[tex]E_{pot}=m*g*h[/tex]

where:

Epot = potential energy [J]

m = mass [kg]

g = gravity acceleration [m/s²]

h = elevation [m]

As we can see, if the body is located at the highest point with respect to the ground, potential energy has the maximum value. Meanwhile, the kinetic energy is zero because there is no movement.

At the lowest point is where the kinetic energy is maximum and the potential energy es zero.

When the body is in the lowest location, the height is zero, therefore potential energy is zero (h = 0). But the body is moving with a certain velocity that is we have kinetic energy.

Answer:

the answer is A

Explanation:

pH is a measure of how acidic/basic water

Answer:

The correct answer is D

Explanation:

The expression for the accelerated ion is

          a =[tex]\frac{v_f - v_o}{ \Delta t}[/tex]

therefore to find the variation of time is needed, which is a data given in the problem.

It also needs to be emptied of speed, which is not given.

Consequently we cannot find the acceleration in this exercise.

The correct answer is D

Answer:

False.

Explanation:

The higher the number in the exertion scale, the more intense the workout.

Answer:

If possessing the ball, players must dribble (not similar to a basketball dribble), or can take up to three steps for up to three seconds at a time without dribbling. No attacking or defending players other than the defending goalkeeper are allowed to touch the floor of the goal area (within six metres of the goal).

Answer:

I think u have to do 580N times 40KG

Answer: DONT MULTIPLY, YOU DIVIDE THEM

Explanation:

F = mass x acceleration

580 N = (40 kg)(a)

580/40 = 14.5

a = 14.5 m/s²
