Is 30 minutes to nine the same as 30 minutes after 8 in life

Answers

Answer 1
Answer: Yes.  In real life, those are both the same time.

If somebody said she'll meet you on the corner at 30 minutes to nine,
and you arrived there at 30 minutes after eight, then you both arrived
on the corner at exactly the same time.  In real life.
Answer 2
Answer: yes it is the same because 30 minutes before 9 is 8:30 and 30 minutes after 8 is 8:30

Is orange juice in an orange potential energy or kinetic energy?

Answers

Answer:

Potential energy.

Explanation:

The potential energy is the energy which is possessed by the body by the virtue of its position with respect to the others, electric charges and with other factors.

And the kinetic energy is defined as the energy of an object which is produced by the virtue of the motion of an object.

Therefore, in the given situation orange juice does not possess any velocity it is in rest. So orange juice is an orange potential energy.
It would be potential energy because it is not moving. 

why do you think accurate measurement of time became possible much after accurate measurement of length and mass

Answers

Accurate measurements of time become possible after accurate measurement of length and mass because time taken by a heavy body to move a certain distance is more,and time taken by a light body to move a certain distance is less.

Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.

Answers

Explanation:

The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.  

Answer:

Sample Response: The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

What TWO things affect the gravitational force acting on an object?

Answers

The strength of the gravitational forces between two masses depends on

--  the product of the masses,

-- the distance between their centers of mass.
mass and distance (between two objects) are those TWO things that affect the gravitational force acting on an object

The sun's apparent motion across the sky from East to West daily is due to theA) rotation of the sun.
B) rotation of the earth.
C) orbit of the earth around the sun.
D) orbit of the sun around the earth.

Answers

Rotation of the Earth contributes to the idea of the Sun setting and rising. The orbit of the Earth around the Sun results in the changing of seasons.

Linh builds a circuit from the diagram shown. A rectangular box of lines with the long side vertical and an extra horizontal line about 2 thirds of the way up. The top line has a circle with an X in it labeled 1. The right side from top has a top circle 2 with an X in it then the connection with the extra line then a bottom circle 4 with an X in it. The extra line has a circle 3 with an X in it. The left side has a stack of horizontal lines near its bottom, which are, from top very short, short, very short, short. If Linh removes bulb 3, which bulbs will remain lit? 1 only

1 and 2 only

4 only

1, 2, and 4

Answers

If Linh removes bulb 3,the bulbs which will remain lit are 1, 2 and 4.

What is circuit?

The electric circuit provided with battery creating potential difference across resistance or capacitor or inductors.

When Linh removes the middle branch, the bulbs 1, 2 and 4 will be acting as resistor which are in series connection. The current flow will be same in all the resistors except 3.

Thus, If Linh removes bulb 3, the bulbs which will remain lit are 1, 2 and 4.
