2. Suppose your car has a maximum braking acceleration of -5 m/s2. Calculate the stopping distance for an initial speed of 25 m/s.
Answer:
s=62.5m
Explanation:
Use the equation v²=u²+2as, where v is the final velocity, u is the initial velocity, a is the acceleration and s is the distance.
0²=25²+2(-5)s
10s=625
s=62.5m
An electric drill transfers some energy wastefully. Aside from heat, what else carries the energy that it transfers wastefully?
Sound and thermal/ heat energy.
Explanation:
Electric drill use electrical energy to convert it into kinetic, but there are some energy waste during the conversion in the form of sound and thermal caused by electric motor.
The waste energy in the electric drill is Copper loss, eddy current loss , sound and Hysteresis loss,

A potential difference of 12Voltage is applied across a resistor of 120resistance the current in the circuit is
Answer:
the current flowing in the circuit is 0.1 A.
Explanation:
Given;
potential difference, V = 12 V
resistance of the circuit, R = 120 ohms
The current flowing in the circuit is calculated as;
V = IR
I = V/R
where;
I is the current flowing in the circuit
I = 12 / 120
I = 0.1 A
Therefore, the current flowing in the circuit is 0.1 A.
A person gets a running start toward a wall from 5 meters away. The person pushes the wall with a force of 500 newtons, but the wall does not move. How much work is done by the person?(1 point)
100 joules
0 joules
2,500 joules
0.01 joule
Answer:
it's 0
Explanation: just took it
The work is done by the person it's 0.
What is Work done?Work on an object when you apply a force to it that causes a change in position for it in the same direction as the applied force.
Force on and displacement of the object are the two basic parts of work done on an object. For a force to exert its force along an object's path of motion, the object must be moved along that path.
When an object is moved across a specific distance by an external force, work is the quantity of energy that is transmitted to the object. The quantity of energy transmitted to an object through work is referred to as the work done on the thing.
Therefore, The work is done by the person it's 0.

What happens to an object when there are no forces acting on it or all the forces acting on it are balanced?
Answer:
It stays and remains at rest
Explanation:
When no forces acts on an object or all the forces on it are balanced, the body stays at rest or remains stationary.
This is based on the Newton's law of inertia which states that "an object will remain in a state of uniform motion or at rest unless an external force acts on it".
If the forces acting on a body is balanced, the object will perpetually remain and keep at rest
Can we always see the same amount of the illuminated side of the Moon from Earth? Explain. Thanks so much for everyone's help! :)
Answer:
Nope.
Explanation:
No. The Moon rotates on its own axis at the same rate that it orbits around Earth. That means we always see the same side of the Moon from our position on Earth. The side we don't see gets just as much light, so a more accurate name for that part of the Moon is the "far side."
No, we can't see the similar quantity of the illuminated side of the Moon from the planet (Earth).
The gravitation of the moon somewhat distorts the form of our entire globe as well as provides us tidal waves. Earth also taps upon that moon, generating a stony and high-threshold "bulge" that faces us.It finished functioning like something of brakes and slowed right down the moon's rotation to the common material, and therefore high moonlight tide confronts us constantly.
Thus the above answer is correct.

Looking across period 4 of the periodic table, potassium (atomic number 19) is followed by calcium (atomic number 20), which is followed by scandium (atomic number 21). Which element should have the largest atomic radius?
A.
potassium
B.
calcium
C.
scandium
D.
All three have the same atomic radius.
Answer:
A. potassium
Explanation:
Potassium is expected to have the greater atomic radius from the given choices of element.
Atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid states of metals.
Across a period, the atomic radii decreases progressively from left to right. This is due to the progressive increase in the nuclear charge without increase in the number of electronic shells.A stone is dropped from the height of 121m and reaches to the earth in 10 sec with an acceleration of 20m/s square find the initial velocity of the stone
As we know that,

V = Final VelocityU = Initial VelocityA = AccelerationS = DistanceAccording to the question,
0² - u² = 2(20)(121)
0 - u² = 4840
-u² = 4840
-u = √4840
u = -69.5 m/s
Answer:-The initial velocity of the stone is -69.5 m/S.

A 1600kg cannon fires a 5kg cannonball horizontally. The exit velocity of the cannonball is 80m/s and the barrel length is 2m. What is the average acceleration of the cannonball before it leaves the barrel?
Answer:
a = 1600 m / s²
Explanation:
For this exercise we use the kinematics relations,
v² = v₀² + 2 a x
where v₀ is the initial velocity of the bullet, which as part of rest is zero, for the distance (x) we can assume that the gases accelerate along the entire trajectory of the cannon x = 2m
a = [tex]\frac{v^2}{2x}[/tex]
let's calculate
a = [tex]\frac{80^2}{2 \ 2}[/tex]
a = 1600 m / s²

A 98 N ball is suspended from a cable so that it hangs 3.5 m above the earth. Find the mass of the ball and the
gravitational PE of the ball.
Answer:
Yes
Explanation:
When you pick something up do you do work to it
Answer:
Simple answer: Yes
Explanation:
Even if you touch an item with a stick you re still doing work to it, most of the time something sitting on a table not being disturbed is having work done to it. Everything has the force of gravity working on it to essentially keep the items from floating away so workis being done to it.
Work done can be something so small (e.g) a pencil sitting on a table) or as big as an earthquake or kicking a ball through a window and smashing the glass.
An engineer wants to increase the load that the three legs of a wooden stool can support. Which of the
following would help to meet that goal?
Answer:
using wood
Explanation:
Which of the following is NOT accelerating?
A ball being juggled.
A women walking at a constant speed of 2.5 m/s along a straight path.
A rocket taking off.
A car slowing down toward a stop sign.
Answer:
3 of them are not accelerating . only one of them is and that one is the rocket taking off because its speed increases
Answer:
Second Option
Explanation:
The answer is the second option or "a women walking at a constant speed of 2.5 m/s along a straight path." Remember that constant means always staying the same so if a women is walking at a constant speed of 2.5 miles per hour on a straight path, she will remain at her current speed at 2.5 mils per hour which isn't acceleration.

help me match the numbers to terms
Answer:
1 represents the electron flow
2 represents the load.
3 represents the voltage source.
4 represents the conductive path.
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
In an electrical circuit, there are various symbols used to represent different parameters or quantities as shown in the image attached above and these includes;
a. 1 represents the electron flow. This is a representation of the direction of flow of current.
b. 2 represents the load. This is the electrical appliance such as an electronic bulb that is being powered by the electrical circuit.
c. 3 represents the voltage source. This is typically a battery cell that provides the required amount of voltage for the circuit.
d. 4 represents the conductive path. This is the conductor that carries current from one point to another in the circuit such as copper.
