Answer:
The object will have an acceleration and the object's velocity will change.
Explanation:
If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.

Where W = weight, m = mass and g = acceleration due to gravity
3. The mass m = 50 kg and g = 9.8 m/[tex]s^{2}[/tex]
Substitute the parameters in the equation above.

Describe how acceleration happens in the context of a collision.
Plz help<3
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
In a collision, both objects are subjected to a force that causes them to accelerate. Despite the fact that the forces are equal in magnitude and direction, the least massive item experiences the highest acceleration. When two objects of identical mass collide, they both experience the same acceleration.
A collision is a brief encounter between two or more bodies that results in a change in motion of the bodies involved as a result of internal forces acting between them. Forces are involved in collisions (there is a change in velocity ).

What is exercise?The advantages of working out vary depending on the type of death a person experiences. Even if a person exercises, excessive sitting can cause a number of illnesses, many of which are fatal. The individual might also engage in mobile activities, in addition, to exercise to improve their fitness.
Any activity that involves bodily motions that increases a person's health, fitness, and well-being while reducing their chance of developing illnesses is considered exercise. It makes it possible for the person to maintain a healthy weight.
Therefore, if an individual whose body composition has little fat and is naturally lean then they have a high metabolism, therefore the correct answer is option A.

A man is on a 30m cliff and throws a ball down with a speed of 7 m/s.
A) With what velocity does the ball hit the ground? B) How high above the ground is the ball after the ball has fallen for 1 second?
Answer:
210
Explanation:
A ball rolls horizontally off the cliff at a speed of 30 m/s. It takes 7 seconds for the ball to hit the ground. What is the height of the cliff and the horizontal distance traveled by the ball?
S = (1/2)*9.8 m/s^2 * 7^2 = 240.1 m if the ball is very dense so air resistance, and therefore terminal velocity, can be ignored.
S = v * t = 30 m/s * 7 s = 210 m for the horizontal distance, again assuming negligible air resistance.
Height above the ground is the ball after the ball has fallen for 1 second is 210 m.
What is speed?The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
A ball rolls horizontally off the cliff at a speed of 30 m/s. It takes 7 seconds for the ball to hit the ground.
S = (1/2)*9.8 m/s² * 7² = 240.1 m if the ball is very dense so air resistance, and therefore terminal velocity, can be ignored.
S = v * t = 30 m/s * 7 s = 210 m for the horizontal distance, again assuming negligible air resistance.
Height above the ground is the ball after the ball has fallen for 1 second is 210 m.

a spacecraft that seems to be motionless in deep space is given some type of quick push. which statement describes what will happen?
An applied force applied causes a body such as the spacecraft to move. The magnitude of the force determines the change in the velocity
What will happen to the spacecraft is given by option C. from among the possible question options.
C. The spacecraft will begin to move and it will continue moving until it is stopped by an equal and opposite force
Reason:
The possible question options obtained from a similar question includes;
A. The spacecraft will move for some time then stop slowly
B. Air resistance will prevent the spacecraft from moving
C. The spacecraft will begin to move and the motion will continue until a force equal and opposite to the applied force stops it
D. The quick push will not cause the spacecraft to move, as a quick push works on Earth only
The state of the space craft = Motionless
Location of the spacecraft = Deep space
Type of force applied = Quick push
The statement that describes what will happen = Required
Solution;
Let F, represent the force applied, and let Δt be the duration of the applied force, we have;
The impulse of the force, F × Δt = m·(v₂ - v₁)
Where;
m = The mass of the spacecraft
v₁ = The initial velocity of the spacecraft = 0
v₂ = Final velocity of the spacecraft
Plugging in v₁ = 0, gives;
F × Δt = m·v₂
The space craft is given a velocity, v₂, and according to Newton's First Law of Motion, it continues moving in a straight line until another force acts on it
Therefore, the correct option is option C. The spacecraft will begin to move and the motion will continue until it is stopped by an equal and opposite force

Write down the relation between force pressure and area
Answer:
Answer: Pressure is directly proportional to force and inversely proportional to area.
Explanation: Pressure is defined as the ratio of force applied to the area of cross section.
Mathematically,
P=\frac{F}{A}P=
A
F
where,
P = Pressure
F = Force applied
A = Area of cross-section
from above it is visible that pressure is directly proportional to the force applied which means that if force increases, pressure increases. It is also inversely proportional to the area of cross-section. So, when area of cross-section increases, pressure decreases.
The units of pressure are N/m^2N/m

and S.I. units for this term is Pascal (P).
what produces pressure in a liquid
Answer:
1. The weight of the column of water above
2. Due to Gravity
(I would say there are two answers for this question)
Explanation:
1.
The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions. For example, the pressure acting on a dam at the bottom of a reservoir is greater than the pressure acting near the top.
2.
Fluid pressure can be caused by gravity, acceleration, or forces in a closed container. Since a fluid has no definite shape, its pressure applies in all directions. Fluid pressure can also be amplified through hydraulic mechanisms and changes with the velocity of the fluid.

The leaves of plants contain specialized parts that absorb energy from sunlight. Which feature would help a plant better compete for sunlight?
leaves that change color
colorful flowers
larger overall leaf size
a shorter stem
Answer:
In most plants, the leaves are the main food factories. They capture the sun's energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.

A. There is positive net force.
B. There is negative net force.

Answer:
B I'm Pretty Sure :DDD
Explanation:
Balanced Forces
In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force. You observed that the object did not move. When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.
