Ahmet hits a baseball that has a mass of 0.14 kg and accelerates it to 600 m/s2. What is the force that was applied?
Answer:
F = 600N
Explanation:
F = m x a
F = Force
m = mass
a = acceleration
F = 0.14 x 600 = 84N

Increasing the amount of current that flows through a wire________ the strength of an electromagnet.
Answer:
increases
Explanation:
edgu2020
Increasing the amount of current that flows through a wire increases the strength of an electromagnet.
What is an electromagnet?An electromagnet is a type of magnet that is created by running an electrical current through a coil of wire. Unlike permanent magnets, which have a fixed magnetic field that cannot be adjusted, the magnetic field of an electromagnet can be turned on and off or adjusted by controlling the amount of current flowing through the coil.
The strength of an electromagnet depends on several factors, including the number of coils in the wire, the amount of current flowing through the wire, and the type of core material used in the coil. Electromagnets are widely used in various applications, such as in electric motors, generators, relays, MRI machines, and particle accelerators.
One of the advantages of electromagnets is that their magnetic field can be easily controlled by adjusting the amount of current flowing through the wire. This makes them useful in applications where the magnetic field needs to be turned on and off, or where a variable magnetic field is required.
Another advantage of electromagnets is that they can be designed to be much stronger than permanent magnets. This is because the strength of an electromagnet is directly proportional to the amount of current flowing through the coil, which can be increased or decreased as needed.
Here in this question,
This happens because an electromagnet is created when an electric current flows through a wire, generating a magnetic field around the wire. The strength of the magnetic field depends on the amount of current flowing through the wire.
When more current flows through the wire, the magnetic field around the wire becomes stronger. This is because the magnetic field is directly proportional to the current flowing through the wire, as well as the number of loops of wire in the coil.
Therefore, increasing the current flowing through a wire in an electromagnet will increase the strength of the magnetic field, resulting in a stronger electromagnet.

Why do you think the electron of the hydrogen atom stays close to the proton in the atom’s nucleus?
Answer:
Electrons are retained by the electromagnetic force in the orbit around the nucleus since the nucleus is positively charged in the middle of the atom and absorbs the electrons charged negatively.
Hope this helps!
We have that for the Question "Why do you think the electron of the hydrogen atom stays close to the proton in the atom’s nucleus" it can be said that
Electron of the hydrogen atom stays close to the proton in the atom’s nucleus because hydrogen with a low proton and electron number its repulsion will be low
From the question we are told
Why do you think the electron of the hydrogen atom stays close to the proton in the atom’s nucleus?
Generally
The electrons are father away from the protons in the nucleus as atomic number increasesThis is because of the law of attraction where unlike charges reply
Therefore
For hydrogen with a low proton and electron number its repulsion will be low and Hence electron of the hydrogen atom stays close to the proton in the atom’s nucleus

Which statements about energy are true?
1.Energy is found only in moving objects.
2.Energy is never created.
3.Energy can move matter.
4.Energy is the same as force.
5.Energy is never destroyed
Answer:
Energy is found only in moving objects : False
Energy is never created : True
Energy can move matter : True
Energy is the same as force : False
Energy is never destroyed : True
Explanation:
Plato
Energy can neither be created nor be destroyed. Energy is generated by both moving and stationary objects but in different forms. Energy can move matter. Hence, options 2, 3 and 5 are correct.
What is energy conservation ?According to the law of conservation of energy, energy can neither be created nor be destroyed. However, it can be transformed from one state to the other. For example electrical energy can be converted to light energy.
Energy is generated in both stationary and moving object. The energy for a particle gained by its motion is called its kinetic energy. The energy stored on an object at rest is called potential energy.
Energy can move matter as well. The energy used to displace an object is called work done on the object. The unit of energy and work done is joule. Therefore, options 2, 3 and 5 are correct.

A baseball is thrown vertically downward from the top of a 155 m tower with an initial velocity of -25 m/s. How long will it take, until it reaches the ground?
Answer:
t = 2.55 s
Explanation:
Given that,
Height from which the baseball is thrown, h = 155 m
Initial velocity of the baseball, u = -25 m/s
We need to find the time taken by it to reach the ground. Let the time is t. Using equation of kinematics to find it as follows:
[tex]v=u+at\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{0-(-25)}{9.8}\\\\t=2.55\ s[/tex]
So, it will take 2.55 seconds to reach the ground.
A rock is kicked horizontally off a dock into the bay 3
times with a higher initial velocity each time as shown to the right. Which of the following statements is true regarding
these scenarios? AND WHY?
(a) The rock takes the longest time to hit the water in
case 3
(b) The rock takes about the same time to hit the water
in each case
(c) The rock hits the water below with the highest speed
in case 1
(d) The rock hits the water with the same speed in each|
case
Student Answer(s):
Student Reasoning:
Answer:
The true statement is;
(b) The rock takes about the same time to hit the water in each case
Explanation:
The given information are;
The direction in which the rock is kicked = Horizontally
The number of different initial horizontal with which the rock as kicked = different horizontal velocity
The time taken for the rock to hit the water is given by the following equation for projectile motion;
y = y₀ + v₀× sin(θ₀)×t - 1/2×g×t²
Where;
θ = The angle the rock makes with the horizontal when it was kicked = 0
y = The height through which the rock drops
y₀ = The initial height of the rock
t = The time taken for the ball to hit the water
g = The acceleration due to gravity ≈ 9.81 m/s²
For the different speeds, v₁, v₂, and v₃, we have;
y = y₀ + v₁× sin(0)×t - 1/2×g×t² = y₀ - 1/2×g×t²
y = y₀ + v₂× sin(0)×t - 1/2×g×t² = y₀ - 1/2×g×t²
y = y₀ + v₃× sin(0)×t - 1/2×g×t² = y₀ - 1/2×g×t²
Therefore, the time it takes for the ball to hit the water is given as follows;
[tex]t = \sqrt{\dfrac{(y_0 - y) \times 2}{g} }[/tex]
Which is the same for each case
However, the speed, v, with which the rock hits the water is given by the following equation;
[tex]v = \sqrt{v_x^2 + v_y^2}[/tex]
[tex]v_y[/tex] = The vertical velocity = v₀ × sin(θ₀) - g×t = v₀ × sin(0) - g×t = -g×t
[tex]v_y[/tex] = -g×t
Therefore, [tex]v_y[/tex], is the same for all three times
While vₓ = v₁, v₂, and v₃, for each of the three times.
Therefore, [tex]v = \sqrt{v_x^2 + v_y^2}[/tex] the speed with which the rock hits the water is different for all three times.

a. 3 m/s
b. 15 m/s
c. 98 m/s
d. 105 m/s
???whats the answers??
The answers is 30 miles per hour, the driver is speeding the car up, section-H, 12 minutes, section-D, and 65 miles per hour.
A car traveling initially at the speed of 30 m/s slows down at the rate of -2m/s^2 for a distance of 60 meters. What is the car’s velocity after covering this distance?
Answer:
Vf = 25.7 [m/s]
Explanation:
To solve this problem we must use the following kinematics equation:
[tex]v_{f} ^{2}= v_{i} ^{2}-(2*a*x)[/tex]
where:
Vf = final velocity [m/s]
Vi = initial velocity = 30 [m/s]
a = desacceleration = 2 [m/s^2]
x = distance = 60 [m]
Note: the negative sign in the equation means that the car slows down.
Now replacing:
[tex]v_{f}^{2}=(30)^{2}-(2*2*60)\\ v_{f}^{2} = 660\\v_{f} =\sqrt{660} \\v_{f}=25.7[m/s][/tex]

Answer:
It would be 2N pointing South.
Explanation:
Since the forces are going in opposite directions, you can subtract them. Which makes it 7N south minus 5N North. That is 2N pointing South. Because the force going south is greater, it is the direction the force will be going.

How long does it take a dropped object to fall 45 meters?
Answer:
If we forget about drag for a second then any object will accelerate at 9.8 m/s/s. The distance traveled is (9.8 m/s)/2 * (x seconds)^2, so solving for 45 meters the no-air fall will take 3.06 seconds and reach 30 m/s or 108 kph or 67.1 mph
