A bmw 23 goes from 0 to 60 miles per hour in 5 seconds . It is also used in the second law of motion
Answer:
Acceleration = 5.3645 m/s²
Explanation:
Given the following data;
Initial velocity, u = 0mph
Final velocity, v = 60 mph
Time, t = 5 seconds
To find the acceleration (also used in the second law of motion), we would use the following formula;
A = (v - u)/t
Conversion:
Miles per hour to meters per seconds;
0 mph = 0 mps
1 mph = 0.44704 mps
60 mph = 60 * 0.44704 = 26.8224 mps
Next, we find the acceleration;
Acceleration = (26.8224 - 0)/5
Acceleration = 26.8224/5
Acceleration = 5.3645 m/s²

newton's second law states that when a net force acts on an object, it accelerates it.Explain how it would be possible for two or more forces to act on object without accelerating it
Answer:
See Explanation
Explanation:
According to Newton's second law of motion, the acceleration of a body is proportional to the net external force that acts on the body.
A body accelerated when it is acted upon by an unbalanced net external force.
When the external forces acting on a body are balanced, the effect of each force is cancelled by the other hence the body is not accelerated according to Newton's second law.

What object currently has the most gravitational potential energy?
A, B, C, or D
Answer:
A
Explanation:
this because
gravitational potential energy = mass x height x gravitational field strength
so let's assume mass is 2 kg and gravitational field strength is 10 N /kg
so when height is very low, take it as 3 m
gravitational potential energy= 2 x 3 x 10 = 60 j
but when height is 6m
gravitational potential energy = 2 x 6 x 10 = 120 j
so when the height is the greatest, the gravitational potential energy is the highest
so A is the heighest so it has the highest gravitational potential energy.
hope this helps

D. The higher temperature decreases the reaction rate, but it also
favors the forward reaction.
Answer: B
Explanation: The higher temperature increases the reaction rate but also favors the reverse read on.
The higher temperature increases the reaction rate, but it also favors the reverse read on. So, option B.
What is meant by rate of a reaction ?The pace at which the products are created from the reactants in a chemical reaction is referred to as the rate of reaction.
Here,
Generally, reactions progress more quickly as the temperature rises.
The average kinetic energy of the reactant molecules will rise with a rise in temperature. The number of molecules having threshold energy rises, increasing the quantity of efficient collisions that actually occur.
Therefore, as the temperature of the reaction is increased, the rate of the reaction increases. But also favors the reverse reaction.
Hence,
The higher temperature increases the reaction rate, but it also favors the reverse read on.

What type of electromagnetic wave has a frequency of around 1012 Hz?
A middle-A tuning fork vibrates with a frequency f of 440 hertz (cycles per second). You strike a middle-A tuning fork with a force that produces a maximum pressure of 5 pascals. Write a sine model that gives the pressure P as a function of the time t (in seconds).A middle-A tuning fork vibrates with a frequency f of 440 hertz (cycles per second). You strike a middle-A tuning fork with a force that produces a maximum pressure of 5 pascals. Write a sine model that gives the pressure P as a function of the time t (in seconds).
Answer:
P = 5sin(880πt)
Explanation:
We write the pressure in the form P = Asin2πft where A = amplitude of pressure, f = frequency of vibration and t = time.
Now, striking the middle-A tuning fork with a force that produces a maximum pressure of 5 pascals implies A = 5 Pa.
Also, the frequency of vibration is 440 hertz. So, f = 440Hz
Thus, P = Asin2πft
P = 5sin2π(440)t
P = 5sin(880πt)
Electrons made to vibrate to and fro at a few hundred thousand hertz emit radio waves. What class of waves is emitted from electron vibrations of a few million billion hertz

A ball rolled 12.0 m [E] in 10.0 s, hit an obstacle, and rolled straight back. After the collision, the ball rolled 8.00 m [W] in 6.00 s. What was the average velocity of the ball?
Answer:
the average velocity of the ball is 5 m/s.
Explanation:
Given;
initial position of the ball, x₁ = 12 m East
final position of the ball, x₂ = 8 m West
initial time of motion, t₁ = 10.0 s
final time of motion, t₂ = 6.0 s
The average velocity is calculated as follows;
[tex]v = \frac{\Delta x}{\Delta t} = \frac{x_1 \ - \ x_2}{t_1 \ - \ t_2}[/tex]
let the Eastward direction be positive
Let the westward direction be negative
[tex]\frac{x_1 \ - \ x_2}{t_1 \ - \ t_2} = \frac{12 \ - \ (-8)}{10 -6}= \frac{20}{4} = 5 \ m/s[/tex]
Therefore, the average velocity of the ball is 5 m/s.

a disturbance that travels through a medium without a transfer of energy and matter
C.
a disturbance that travels through a medium with a transfer of energy and without a transfer of matter
D.
a disturbance that travels through a medium with a transfer of matter and without a transfer of energy
E.
a disturbance that travels only in the absence of a material medium
Answer:
C. a disturbance that travels through a medium with a transfer of energy and without a transfer of matter
Explanation:
A wave is any disturbance that transfers energy from one location to the other via a substance called medium. It is important to note that a wave only conveys energy and not matter. For example, sound wave is a type of wave that carries sound energy from one place to another via mediums such as water, air etc.
Hence, according to this question, a wave can be described as a disturbance that travels through a medium with a transfer of energy and WITHOUT A TRANSFER OF MATTER.

Two asteroids are located a certain distance away from each other. They have the same mass . The gravitational force of attraction is f . If the mass of one of the asteroids is doubled, how will the gravitational force be affected
Answer:
F' = 2F
Explanation:
The gravitational force of attraction between asteroids is given by Newton's Law of Gravitation:
[tex]F = \frac{Gm_1m_2}{r^2}[/tex]
where,
F = Force
G = Universal Gravitational Constant
m₁ = m₂ = m = mass of each asteroid
r = distance between asteroids
Therefore,
[tex]F = \frac{Gm^2}{r^2}[/tex] --------------------- eq(1)
Now, if we double the mass of one asteroid:
[tex]F' = \frac{G(2m^2)}{r^2} \\\\F' = 2\frac{Gm^2}{r^2}[/tex]
using equation (1):
F' = 2F

You have a grindstone (a disk) that is 98.0 kg, has a 0.335-m radius, and is turning at 100 rpm, and you press a steel axe against it with a radial force of 23.6 N. Assuming the kinetic coefficient of friction between steel and stone is 0.192, calculate the angular acceleration of the grindstone.
Answer:
[tex]a=0.276[/tex]
Explanation:
From the question we are told that:
Mass [tex]m=98.kg[/tex]
Radius [tex]r=0.335[/tex]
Angular velocity [tex]\omega=100rpm[/tex]
Radial force of [tex]F_r=23.6 N.[/tex]
Kinetic coefficient of friction [tex]\mu=0.192[/tex]
Generally the equation for Kinetic Force is mathematically given by
[tex]F_k=\mu.F_r[/tex]
[tex]F_k=0.192*23.6[/tex]
[tex]F_k=4.5312[/tex]
Generally the equation for Torque on Center is mathematically given by
[tex]Ia=f_k*r[/tex]
Where
[tex]I=\frac{Mr^2}{2}[/tex]
Therefore
[tex]a=\frac{2f_k}{Mr}[/tex]
[tex]a=\frac{2*4.5312}{98*0.335}[/tex]
[tex]a=0.276[/tex]
Therefore Angular acceleration of the grindstone is
[tex]a=0.276[/tex]
4. A car accelerates at 2.5 m/s^2, covers 4 km in 0.8 min. How fast was it moving at the beginning
of the time interval? *
Answer:
Initial velocity, u = 23.33 m/s
Explanation:
Given the following data;
Acceleration = 2.5 m/s²
Distance = 4 km to meters = 4000 meters
Time = 0.8 mins to seconds = 0.8 * 60 = 48 seconds.
To find the initial velocity, we would use the second equation of motion;
[tex] S = ut + \frac {1}{2}at^{2}[/tex]
Where;
S represents the displacement or height measured in meters.
u represents the initial velocity measured in meters per seconds.
t represents the time measured in seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
4000 = u*48 + ½*2.5*48²
4000 = 48u + 1.25*2304
4000 = 48u + 2880
48u = 4000 - 2880
48u = 1120
Initial velocity, u = 1120/48
Initial velocity, u = 23.33 m/s
Gravity is the force that objects exert on each other because of their masses. The strength of the gravitational force between two objects
depends on two factors, mass and distance. How is gravity related to mass and distance? Choose ALL the statements that apply.
If one of the masses is doubled, the force of gravity between the objects is doubled.
As distance between the objects increases, the force of gravity decreases.
As distance between the objects increases, the force of gravity increases.
The more mass two objects have, the less the force of gravity the masses exert on each other
Greater mass results in greater force.
Explanation:
Newton's law of universal gravitation states that the force of gravity affects everything with mass in the universe. Newton's law also states that the strength of gravity between any two objects depends on the masses of the objects and the distance between them
Why do the planets orbit the Sun in an elliptical shape?
Answer:
That's essentially how objects in orbits work as they move closer to the body they orbit, they accelerate faster and faster. Our penny will get so fast that, once it comes around the planet, it will be flung very far away, which will then slow it down. This is what creates an elliptical orbit.
