If an object has an increasing positive acceleration, what can we assume about the forces on it?

Answers

Answer:

F = M a    is a vector equation

F has the same sign as A and is in the same direction as the vector a

If a is positive then F must also be positive

If an object has an increasing positive acceleration, then  we can assume that there is some unbalanced increasing force acting on it as the force is the product of the mass of the object and the acceleration.

What is Newton's second law?

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

The acceleration of an item rises proportionately to the force applied to it. So, doubling the force also doubles the acceleration.

Since the force is equal to the product of the item's mass and acceleration, if an object is moving at an increasing positive acceleration, we may infer that there is an imbalanced growing force acting on it.

A boy is watching his grandfather fire an old cannon. He notices that whenever the
cannonball is fired, it moves with a very high velocity to the right. He also notices
that when the cannonball is fired, the cannon moves very slowly to the left. How
does conservation of momentum explain these observations?
v cannon
V cannonball
Since the motions of the cannon and cannon ball were caused by the same
event, they must have equal and opposite momentum. Since the cannon has
much more mass, it will have a larger velocity.
The total momentum of the system was zero before the cannon was fired, so
the cannonball and cannon must have equal and opposite momentum. Since
the cannon has much more mass, it will have a smaller velocity.
The cannon gave momentum to the cannon ball, so they both begin to move.
Since the cannon has much more mass, it will have a smaller momentum.
The cannon gave momentum to the cannon ball, so they both begin to move.
Since the cannonball has much less mass, it will have a smaller momentum.

Answers

Answer:

since the cannon ball has much less mass it will have a smaller momentum.

The system's total momentum was zero before the cannon was fired, the momentum of the cannonball and the cannon must be equal and opposing. Since the cannon has much more mass, it will have a smaller velocity.

What is momentum?

The combination of a particle's mass and velocity produces momentum. Momentum has both a direction. The force exerted on a particle is equated to the time rate of change of momentum by Isaac Newton's second equation of motion.

Since there is no external force acting on the system, momentum ought to be conserved in accordance with the law of conservation of momentum.

Since we are aware that momentum is determined by a formula

M = [tex]mass * velocity[/tex]

Here M is the momentum.

Since the system's total momentum was zero before the cannon was fired, the momentum of the cannonball and the cannon must be equal and opposing. The cannon will have a lower velocity because it has a lot greater mass.

a golfer can hit a golf ball 300 m horizontally. what maximum height would a 301.5 meter drive reach if it was launched at a 25 degree angle above the ground​

Answers

This question involves the concepts of projectile motion, horizontal range, and height.

The maximum height reached by the ball is "35.15 m".

First, we will find out the launch velocity of the projectile motion of the ball, by using the formula of the horizontal range:

[tex]R= \frac{u^2Sin\ 2\theta}{g}\\\\[/tex]

where,

R = horizontal range = 301.5 m

u = launch speed = ?

θ = launch angle = 25°

g = acceleration due to gravity = 9.81 m/s²

Therefore,

[tex]301.5\ m = \frac{u^2Sin\ 50^o}{9.81\ m/s^2}\\\\u = \sqrt{\frac{(301.5\ m)(9.81\ m/s^2)}{Sin\ 50^o}}[/tex]

u = 62.14 m/s

Now, we will find out the maximum height (H) of the projectile motion, using the following formula:

[tex]H = \frac{u^2Sin^2\theta}{2g}\\\\H =\frac{(62.14\ m/s)^2Sin^2(25^o)}{2(9.81\ m/s^2)}[/tex]

H = 35.15 m

1. How does the mass of Jupiter compare to Earth?
2. How quickly does it rotate on its axis?
3. What makes the different bands on the planet?

Answers

Answer:

1.

Jupiter is the largest planet in the solar system. (Image credit: NASA)

The largest planet in the solar system, the gas giant Jupiter is approximately 318 times as massive as Earth. If the mass of all of the other planets in the solar system were combined into one "super planet," Jupiter would still be two and a half times as large.

2.Rotation of Jupiter

[/caption]

Jupiter has the fastest rotation of all the planets in the Solar System, completing one rotation on its axis every 9.9 hours.

3.Jupiter, the King of the Planets, is a gas giant, which means that it's made mostly of gases like hydrogen and helium, and that it doesn't have a solid surface in the way that rocky planets like Earth do. With a temperature of 130 K (-140 C, -230 F), it's so cold that it gives off most of its energy in the infrared. In fact, Jupiter gives off almost twice as much heat as it receives from the Sun. It's able to do this because it has its own internal heat source, powered by the slow gravitational collapse that started when the planet first formed. Astronomers estimate that Jupiter is currently shrinking by almost 2 cm per year

a ball is thrown upward at an angle what causes the change in the balls velocity?

Answers

Answer:

When a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.

an object is thrown with an initial speed v near the surface of earth. assume that air resistance is negligible and the gravitational field is constant. if the object is thrown vertically upward, the direction and magnitude of its acceleration while it is in the air is

Answers

Hi there!

a = -9.81 m/s²

When throwing a ball into the air (ignoring air resistance), the acceleration in the vertical direction is ALWAYS constant and equal to the acceleration due to gravity.

In this instance, the acceleration due to gravity is downward, resulting in the object falling. So, we must put a negative sign:

Thus, a = -9.81 m/s².

An object is pulled up an incline plane at a constant velocity as the picture above shows. Calculate the tension on the rope.
A. 377 N
B. 502 N
C. 305 N
D. 545 N

Answers

Hi there!

[tex]\large\boxed{545N}[/tex]

Since the object is being pulled at a constant velocity, the forces must be balanced.

Since there is no movement vertically, we must take into account the horizontal forces. We can also assume a positive acceleration to be in the direction of motion.

The acceleration and force due to gravity on an incline is:

a = gsinФ

F = MgsinФ

∑F = -MgsinФ + T

Since it is getting pulled at a constant velocity, ∑F = 0. So:

0  = -MgsinФ + T

MgsinФ = T

Solve for T by plugging in values. Let g = 10 m/s²

T = (120)(10)sin(27) ≈ 545 N

How does resistance affect the flow of current in a connecting wire?​

Answers

Answer:

Resistance affect the flow of current in a connecting wire because there is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse.

what is the purpose of the magnetic field in a cathode ray tube?

Answers

Answer:

In order to determine if the cathode ray consisted of charged particles, Thomson used magnets and charged plates to deflect the cathode ray. He observed that cathode rays were deflected by a magnetic field in the same manner as a wire carrying an electric current, which was known to be negatively charged.

Explanation:

According to the right-hand rule, the magnetic field causes the electrons to be refracted. Turn on the power strip to learn about the Cathode Ray (electron beam) Deflection by an Electric Field.

What is Magnetic Field?

Magnetic forces can be seen in a magnetic field, an electric current, a changing electric field, or a vector field around a magnet. Magnetic compass needles and other permanent magnets align in the direction of magnetic fields like the one found on Earth. Electrically charged particles are forced to move in a circular or helical pattern by magnetic fields. The operation of electric motors is caused by this force, which is applied to electric currents in wires in a magnetic field.

The Lorentz Force, which is explained by the left-hand rule, has an impact on what happens inside the tube. In accordance with this law, an electron or other charged particle travelling in a magnetic field will be deflected by the field at a right angle to both the field's direction and the direction of the particle.
