Which of the following substances conducts electricity?
A. A block of salt
B. Distilled water
C. Sugar
D. Vinegar
Answer:
a
Explanation:
salt and energy can cause reactions to produce electricity
Answer: The answer is A
Explanation: An electrolyte solution has the ability to conduct electricity because when a salt dissolves, its dissociated ions can move freely in solution, allowing a charge to flow. Electrolyte solutions are normally formed when a salt is placed into a solvent such as water. (Google Source If needed)

Convert (76)10 into Binary.
Answer:
The base-10 value of 76(10 )
is equal to base-2 value of 10011002.
Explanation:
Step 1) Divide 76 by 2 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.
Step 2) Divide the Whole part of the Quotient from Step 1 by 2. Again, keep the Whole part and set the Remainder aside.
Step 3) Repeat Step 2 above until the Whole part is 0.
Step 4) Write down the Remainders in reverse order to get the answer to 76 as a binary.
Here we will show our work so you can follow along:
76 / 2 = 38 with 0 remainder
38 / 2 = 19 with 0 remainder
19 / 2 = 9 with 1 remainder
9 / 2 = 4 with 1 remainder
4 / 2 = 2 with 0 remainder
2 / 2 = 1 with 0 remainder
1 / 2 = 0 with 1 remainder
Then, when we put the remainders together in reverse order, we get the answer. The decimal number 76 converted to binary is therefore:
1001100

What integer represents the total charge of 4 protons
Answer:
4
Explanation:
+ 4 is the integer that represents the total charge of 4 protons because proton has a positive charge is known as cation so plus sign should be added to number of protons while on the other hand, for 4 electrons we -4 integer because electron has negative charge is known as anion so that's why plus sign is added with proton and negative sign is added to electron.

Acceleration due to gravity on the moon is greater / less than acceleration due to gravity on Earth. The mass of an object on the moon is less than / greater than / the same as it is on Earth. Using the equation F = ma to calculate weight, the mass of an object is multiplied / divided by acceleration due to gravity. So, the weight of an object on the moon is greater / less than the weight of the same object on Earth.

When someone is riding on an amusement ride also known as a roller coaster, due to the nature of the turns and slope, energy will change from potential to kinetic energy and it will be repeated a couple of times throughout the the course of the ride.
Now, Kinetic energy is the one that is used during motion.
Normally, the amusement ride vehicles will be pulled up from the first hill by a chain and as the other vehicles follow that route in climbing, and they will then gain potential energy.
The branch of science which deals with chemicals is called chemistry.
The energy formed in a system by the motion of particles is called kinetic energy. which is half of the product of the mass and volume.
For example - When someone is riding on an amusement ride also known as a roller coaster, due to the nature of the turns and slope, energy will change from potential to kinetic energy and it will be repeated a couple of times throughout the course of the ride.
The energy stored in the system when it's at a rest is called potential energy, the energy is converted into kinetic energy when it starts moving. The potential energy is stated as the product of the mass, height, and acceleration due to gravity.
For example - Normally, the amusement ride vehicles will be pulled up from the first hill by a chain and as the other vehicles follow that route in climbing, and they will then gain potential energy.For more information, refer to the link:-

Parker has a toy car he has made out of plastic building blocks. He breaks it apart so he can build something different with the same blocks. When he breaks the blocks apart, which stage of the carbon cycle is he best demonstrating?
A:carbon atoms dissolving in the oceans
B:producers removing carbon from the atmosphere
C:organisms decay and carbon atoms return to the soil
D:consumers use carbon atoms to build body structures
Answer:C
Because Parker is using the recycled blocks (carbon atoms) and essentially returning them to their original state (which is "the soil"). When the clocks break apart, that is the organisms decaying.

Studying energy involves determining the amount of energy an object has. This energy can be kinetic or potential, or it could be a combination of both. Consider a 2-kg bowling ball sits on top of a building that is 40 meters tall. It falls toward the ground. Think about the amounts kinetic energy the bowling ball has as it falls, select the when the ball would have the most kinetic energy from the choices given.
Question 1 options:
as it is just about to hit the ground from a fall off a building that is 40 meters tall and traveling 28 meters per second.
as it sits on top of a building that is 40 meters tall.
after it hits the ground and is no longer moving.
as it is half way through a fall off a building that is 40 meters tall and traveling 19.8 meters per second.

Answer: l believe “as it is just about to hit the ground from a fall off a building that is 40 meters tall and traveling 28 meters per second.” is when the bowling ball will have the most kinetic energy because kinetic energy is all about energy that something has while it’s in motion and with the bowling ball traveling at 28 meters per second it has the greatest energy out of the rest of the options.

To find time, t, the age of the universe, you must first isolate the variable t. Rewrite the velocity equation v = d / t so that you are solving for time.
Answer:
t = d/v
Explanation:
All you have to do is the inverse operation so that you multiply by "t" and it will be on the side with the "v" then you divide the v and it will be under the "d" so time = distance/ velocity (speed)
To find time, t, the age of the universe, you must first isolate the variable t. The velocity equation is t = d / v.
What is velocity?Velocity is defined as a directional speed of a object in motion as an indication of its rate of change in position as observed for a particular frame of reference and as measured by a particular standard of time. It is a vector quantity.
Velocity can also be defined as the rate at which an object's position changes in relation to a frame of reference and time.
There are various types of velocity some are
Uniform velocityVariable velocityAverage velocityInstantaneous velocityVelocity can be expressed as
Velocity = Displacement / Change in time
Thus, to find time, t, the age of the universe, you must first isolate the variable t. The velocity equation is t = d / v.
