Answer:
B
Explanation:
if you want to change an object's momentum you need to apply force to the object
This equation tells the position of the ball, x, at any time t. Let's use it to solve for the position of the ball at t=0.00231 s. What value do you get when you use t=0.00231 s and solve for the position, x?
The slope of the graph, A, and the starting position of the ball, B, can be used to determine the position of the ball
The position of the ball at time t = 0.00231 s is 59.933 cmReason:
Question; The possible function representing the given equation is presented as follows;
x = A·t + B
Where;
A = 2.59 × 10⁴ [tex]\frac{cm}{s}[/tex]
B = 0.104 cm
t = Time in seconds (s)
x = The position (cm)
Required: The value of the position when t = 0.00231 s
Solution:
The position time graph of an object moving with a constant speed is a straight line with an equation of the form y = m·x + c
Plugging in the value of t = 0.00231 in the given equation gives;
x = 2.59 × 10⁴ × 0.00231 + 0.104 = 59.933
The position x of the ball at time, t = 0.00231 s is 59.933 cm

How is air resistance similar to gravity? give me two ways.
Answer:
1. they both act on an object in free fall
Explanation:
2. both help determine how fast the object will accelerate
EXPLAIN: Why must you reduce friction
order to move certain objects?
Friction is one of the forces working against a moving object, it makes it harder to move the more friction is exerted on the object. So, by reducing friction, you are making it easier for you to be able to move objects.

In physics, electromagnetic radiation is defined as waves created as a result of the electromagnetic field vibratons moving through space, carrying electromagnetic energy. The waves produced includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays.
The character of an electromagnetic wave is dependent on its frequency or wavelength making each electromagnetic spectrum having their own range of uses.
For transmitting signals, Radio waves as well as Microwaves is useful , while the former help transmit Information through radio and TV stations the later is used in satellite communications, this is because

if a 5,000 investment earn $1,575 interest over over 18 years what is the annual interest rate
Answer:
I = 1575 / 5000 = 31.5 % interest on investment
(1 + i)^18 = 1.315 where i interest is earned per year
One can use logs or
1 + i = 1.315^1/18 = 1.0153
So the annual interest rate is .0153 or 1.53%
Or
5000 (1 + i)^18 = 6575
(1 + i)^18 = 1.315
18 log (1 + i) = log 1.315
log (1 + i) = .006607
1 + i = 1.0153
i = .0153 = 1.53%

Legend has it that a young Isaac Newton was sitting under an apple tree when he was bonked on the head by a falling piece of fruit, a 17th-century “aha moment” that prompted him to suddenly come up with his law of gravity.
An elevator accelerates upward at 1.2 m/s 2 . the acceleration of gravity is 9.8 m/s 2 . what is the upward force exerted by the floor of the elevator on a(n) 62 kg passenger? answer in units of n.

What is Newton's first law of motion?
A. For every force there is an equal and opposite reaction force.
B. If a net force is applied to an object, then the object will accelerate.
C. An object will remain at rest or continue moving in a straight line with a constant speed unless acted on by an unbalanced force.
D. The gravitational force between two objects is proportional to their masses and inversely proportional to the distance between them.
Answer:
C
Explanation:
Newton's first Law of Motion is also known as law of inertia, which states that "an object at rest remains at rest, and an object that is moving will continue to move straight and with constant velocity, if and only if there is no net force acting on that object". As such, the correct option should be C.
Option A is Newton's third Law of Motion.
Option B is Newton's second Law of Motion
Option D is Newton's Law of Universal Gravity

According to Newton’s first law of physics, which explains what happens to a baseball when it is hit with a bat?
OPTIONS:
A.
The course of the ball cannot be changed as long as it remains in motion.
B.
The ball lacks force or momentum but gets momentum when it hits an unbalanced force.
C.
The ball is an unbalanced force and can only have its course altered by a stationary object.
D.
The ball is traveling at a steady speed until it hits an unbalanced force and changes direction.
PLEASE NO LINKS
Answer:
Your answer will be D.
The ball is traveling at a steady speed until it hits an unbalanced force and changes direction.
Explanation:
The ball is traveling at a steady speed until it hits an unbalanced force and changes direction. The correct option is D.
Thus, An unbalanced external force acts upon an item, Newton's first law of motion, often known as the law of inertia, asserts that an object at rest will remain at rest and an object in motion will continue to move in the same direction and at the same pace.
When a baseball is struck with a bat, it is originally at rest or moving steadily forward.
The ball experiences an imbalanced force when it is struck by the bat, altering its direction and speed. The bat's application of external force is what causes this shift in motion.
Thus, The ball is traveling at a steady speed until it hits an unbalanced force and changes direction. The correct option is D.

A rubber duck sat is floating on the surface
on the water. 10N of weight is acting
DOWNWARDS on the water. What other
force must be acting to allow the duck to
float?
The other force that must be acting on the duck is upthrust of 10 N.
The given parameters;
weight of the rubber duck, W = 10 NWhen the weight of the object is equal to the upthrust, the apparent weight will be zero and the object will float in the liquid. This is known as principle of floatation.
Since the given weight of the rubber duck is 10 N, then the upthrust on the duck will be 10 N to enable the duck float on the water.
Thus, the other force acting on the duck is upthrust of 10 N.

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.
