Question 55. What subatomic particle has no electrical charge?
•neutron
•proton
•electron
•atom

Answers

Answer 1

Answer:

Answer: A Neutron.

I know this is correct. Thank's and yw :3

Answer 2

Answer: Neutrons have no electrical charge

protons have a positive charge

electrons have a negative charge

Atoms mainly consist of a positively charged nucleus surrounded by one more negatively charged electrons, but overall the atom has no charge so it would neutral!

hope this helps!!

In Act III, Scene 1, who hears these words from Titania?Thou art as wise as thou art beautiful.
A. Puck
B. Oberon
C. Bottom
D. Peaseblossom

Answers

C. Bottom

Titania speaks these words as she is under the enchantment of the magic flower, it makes her fall in love with the first thing she sees. It's comedic because Bottom is also enchanted to have the head of a donkey, so she's claiming that this peasant with a donkey head is both wise and beautiful. The reality being that he is as wise as he is beautiful, in that he is neither beautiful nor wise.

All of the following are examples of ways to improve energy efficiency of heating systems, except _______.A. Closing off rooms that aren’t in use.
B. Frequently cleaning the furnace filter.
C. Fixing cracks in the walls and floor.
D. Opening the front door in winter to filter and clean warm air.

Answer:

D. Opening the front door in winter to filter and clean warm ai

Explanation:

All of the following are examples of ways to improve energy efficiency of heating systems, except _______.

A. Closing off rooms that aren’t in use.

B. Frequently cleaning the furnace filter.

C. Fixing cracks in the walls and floor.

D. Opening the front door in winter to filter and clean warm air

for an heating systems it is better to keep the front door shut so that all the heat energy does not escape outside.

when heat energy is within a closed system ,it can still be utilized to keep the inhabitants warm otherwise there will be an exchange with the cold from winter fall outside the air, and the heating system's efficiency will be reduced

Charles is having a lot of problems with errors in a very complicated spreadsheet that he inherited from a colleague, and he turns to another co-worker, Seymour, for tips on how to trace errors in the sheet. If Charles sees which of the following, Seymour explains, there is a mistyped function name in the sheet.a.#FORM?
b.#NAME?
c.#####
d.#FNCT?

Answers

Answer:

b.#NAME?

Explanation:

Remember, in Spreadsheet programs like Ms Excel several types of errors can occur such as value error.

However, since Seymour explains that there is a mistyped function name in the sheet it is more likely to display on the affected cell as #NAME?.

For example the function =SUM is wrongly spelled =SOM.

Therefore it is important to make sure the function name is spelled correctly.

H20 is water.
1. Water in a solid form is ice. (when it is frozen)
2. Water in a gas form is steam, or water vapor. (when it evaporates)
3. Water in a liquid form is water. (not frozen, not evaporated)
4. A solid is a state of matter that has a fixed or definite shape in volume. (it cannot change its shape)
5. A liquid is a state of matter that has a fixed or definite shape in volume but takes the form of its container. (it can change shape, but is affected by gravity and will spread when given the option)
6. A gas is a state of matter that has no definite shape or volume. (it floats and is too spread out to contain or measure)
7. The particles of a gas have less attraction between them than the particles of the same substance in liquid or gas form. (gas particles are spread out farther, not having as much attraction to other particles)
9. Melting is a change in state of matter from a solid to a liquid. (like when water melts from ice to normal water)
10. Freezing is a change in state of matter from a liquid to a solid. (like when you make ice cubes out of putting water in the freezer)
12. Below the boiling point
13. Condensation is a change in state of matter from a gas to a liquid (like the water that forms drops on the pan lid when you boil water)
14. Sublimation is a change in state of matter from a solid to a gas (like when it's really cold outside, and the snow disappears from the roof without melting and causing puddles)
15. The freezing point of a substance is the same as the melting point of a substance.
16. The condensation point of a substance is the same as the dew point of a substance.

Different velocity-time graph lines are shown, displaying the behavior of multiple race carts along a linear track.Which description correctly identifies cart C?

A) Has a positive acceleration and is speeding up.
B) Moving with zero acceleration.
C) Moving at a constant acceleration.
D) Has a negative acceleration and is slowing down.

Answers

B) Moving with zero acceleration.

Explanation:

Acceleration is defined as the rate of change of the velocity per unit time:

$a=(\Delta v)/(\Delta t)$

In a velocity-time graph, this ratio corresponds to the slope of the curve. In fact:

$\Delta v$ (change in velocity) corresponds to the increase in the y-axis

$\Delta t$ (change in time) corresponds to the increase in the x-axis

So, acceleration corresponds to the slope of the curve in a velocity-time graph. For cart C, the slope is zero, therefore the acceleration is also zero.

Answer:

B) Moving with zero acceleration.

Explanation:

As we can see the graph for Cart C that its velocity is constant and not changing its magnitude as well as its sign

So here the magnitude and direction is constant so we can say that velocity will remain constant always.

Where we can define the acceleration as

$a = (dv)/(dt)$
