2. If Peter is traveling .25 m/s on his bike, how long will it take him to reach
a fence that is 12 meters away?
a. 3 s
b. 20 s
c. 12 s
d. 48 s
Answer:
48 seconds
Explanation:
Since S=d/t, plug in the known values and solve
0.25m/s=12m/t
0.25m/s*t=12m
t=12m/0.25m/s
t=48 seconds

Why does jake get shocked when he touches the top on the plastic slide but Jacob doesn’t get shocked when he touches the underside?
Answer:
Physics and sun. BOOM
Answer: As you slide down the plastic slide, electrons move from the plastic to you. Now you have extra electrons. Touch another person or an object (anything that isn't negatively charged by extra electrons) and ZAP!
technically, since no one is sliding down the other side of the slide there aren't any extra electrons being made, so you can't really get shocked.

A liquid has a density of 0.85 g/cm. If you pour some of the liquid into a glass of water, will the liquid float?
Explain how you know
PLEASE HURRY
Answer:
Yes, it will float.
Explanation:
It is given that,
A liquid has a density of 0.85 g/cm³.
We know that, the density of water is 1 g/cm³.
The density of the liquid is less than that of water. If the density of the liquid is less than that of water, it will float in it. Hence, if you pour some of the liquid into a glass of water, it will float.

Allison pulls on a refrigerator with 200 N of force. Fred helps
her out and pulls on the refrigerator in the same direction with
300 N of force. What is the net force on the refrigerator?
N
Answer:500
Explanation:
If two forces are acting on an object in the same direction, then they will add up and the net force will be the sum of their magnitudes. Thus, the net force on refrigerator is 500 N.
What is force?Force is an external agent acting on a body to deform it or to change it form the state of rest or motion. There are various kinds of forces, such as gravitational force, frictional force, magnetic force etc.
If two forces are acting on a on an object in the same direction, then they will add up and the net force will be the sum of their magnitudes. If they are acting from the opposite directions, they will cancel each other in magnitude and and the net force will be the subtracted value.
Here, both Allison and fred pulls the refrigerator from the same direction and the net force is the sum of forces by each person. Therefore, the net force here is 300 + 200 = 500 N.

The Washington Monument in our nation's capital is 555 ft high. Neglecting the effects of air resistance, what would be the
speed of the penny as it "hit" the ground?
оа
Ob
Oc
Od
48.3 m/s
-68.4 m/s
84.7 m/s
-57.6 m/s
Answer:
a= g = - 9.81 m/s2.
The following equations will be helpful:
a = (vf - vo)/t d = vot + 1/2 at2 vf2 = vo2 + 2ad
When you substitute the specific acceleration due to gravity (g), the equations are as follows:
g = (vf - vo)/t d = vot + 1/2 gt2 vf2 = vo2 + 2gd
If the object is dropped from rest, the initial velocity ("vi") is zero. This further simplifies the equations to these:
g = vf /t d = 1/2 gt2 vf2 = 2gd
The sign convention that we will use for direction is this: "down" is the negative direction. If you are given a velocity such as -5.0 m/s, we will assume that the direction of the velocity vector is down. Also if you are told that an object falls with a velocity of 5.0 m/s, you would substitute -5.0 m/s in your equations. The sign convention would also apply to the acceleration due to gravity as shown above. The direction of the acceleration vector is down (-9.81 m/s2) because the gravitational force causing the acceleration is directed downward.

1. What is responsible for the different phases of matter?
2. What is the temperature at which a substance changes from a liquid to a solid?
3. What is the phase change from a gas to a liquid?
4. What is the phase change from a solid directly to a gas?
Answer:
1. The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.
2. The temperature at which a substance changes from the liq- uid state to the solid state is called the freezing point. The freez- ing point of the liquid state of a substance is the same temperature as the melting point of the solid state. For example, solid water melts at 0°C and liquid water freezes at 0°C.
3. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation. 4. Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.

a roller coaster begins at the top of a hill if it acelerates at the rate of 2 m/s2 and has a mass of 2000 kg what net force is acting on it plzzz someone help im over here crying bc i dont know
Answer:
[tex]\boxed {\boxed {\sf 4000 \ Newtons }}[/tex]
Explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F=m*a[/tex]
The mass of the roller coaster is 2000 kilograms and the acceleration is 2 meters per second squared.
[tex]m= 2000 \ kg \\a= 2 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 2000 \ kg * 2 \ m/s^2[/tex]
Multiply.
[tex]F= 4000 \ kg*m/s^2[/tex]
1 kg*m/s² is equal to 1 NTherefore our answer of 4000 kg*m/s² is equal to 4000 Newtons[tex]F= 4000 \ N[/tex]
The net force acting on the roller coaster is 4000 Newtons.

If magnetic field lines are drawn to represent a magnetic field, what would
they look like?
A. Only some of the lines form loops.
B. There is no consistent pattern in the lines.
C. The lines extend from the north pole to the south pole of the
magnet.
D. The lines extend from the south pole to the north pole of the
magnet.
Answer:
c
Explanation:
magnetic lines moves from North to South Pole of a magnet
The magnetic field lines are drawn to represent the start from the north pole to the south pole of the magnet. Therefore, option (C) is correct.
What are magnetic field lines?The magnetic field can be described as a field generated by the magnet or electric charges in motion. The magnetic field can be defined as the region around a magnetic material within which the force of magnetism acts.
Magnetic fields can be represented using magnetic field lines. Magnetic field lines can be drawn with the help of a compass needle. The tangent can be drawn to the magnetic field lines giving the direction of the magnetic field.
Magnetic field lines appeared to emerge from the north pole and merge at the south pole. The direction of the magnetic field lines is from the south pole to the north pole inside the magnet.
Magnetic field lines never intersect and form a closed loop. Field lines have both magnitude and direction so they are represented by a vector.
