2. What happens when multiple forces act on an object?A. The object will always move.
B. The object will move if the forces are balanced.
C. The object will move if the forces are unbalanced.
D. The object will always stay in place.
3. An object moves in the direction of the __________ force.
A. net
B. balanced
C. strongest
D. weakest

Answers

Answer 1

Answer: 2) The correct answer is option C i.e. The object will move if the forces are unbalanced. The objects move only on the application of unbalanced forces. 3. The correct answer is option A. i.e. net An object moves in the direction of the net force. The object moves in the direction of resultant or net force.

Which was a testable idea that Ernest Rutherford developed in his experiments?- The positive charge in an atom is concentrated in one location.
- Atoms are not divisible into smaller particles.
- It is impossible to define the mass of an atom.
- The atom contains no particles that have a neutral charge.

Answers

Answer:

- The positive charge in an atom is concentrated in one location.

Explanation:

In Rutherford's experiment when alpha particles are projected towards the gold foil then he observed that major proportion of the alpha particles are moved out undeviating.

This shows that alpha particles which are positively charged are not repelled by other positive charge of nucleus as it is concentrated at small part of atom

because very few alpha particles are reflected back at 180 degree so he concluded that nucleus charge is concentrated at very small space

and that part is termed as nucleus.

so correct answer is

- The positive charge in an atom is concentrated in one location.

The answer is
The positive charge in an atom is concentrated in one location.

Which region of the Sun is typically about 6,000C?photosphere
corona
core
radiative zone
chromosphere
convective zone

Answers

The correct answer to the question is : Photosphere i.e it is the region whose temperature is 6000 degree celsius.

EXPLANATION:

The Sun has many regions starting from photosphere to central core. Different regions of the sun has different temperature.

The temperature of the sun is due to the fusion occurring inside it. The core temperature is immense due to the gravitational attraction which produces more heat there. Gradually the temperature decreases as we move away from the sun core.

As per the question, the temperature is given as 6000 degree celsius.

The region of the sun which corresponds to this temperature is photosphere. The temperature of photosphere varies from 5500 degree celsius to 7500 degree celsius. The temperature of sunspots found in the sun may be lower than the average temperature of the photosphere.

Hence, the correct answer is Photosphere.

So we want to know which region of the sun is tipically around 6000 degrees Celsius. So in the core of the Sun, the temperature is around 15000000 degrees Celsius and as we move towards the surface we get to the photosphere where the temperature is around 6000 degrees Celsius.

John’s mass is 91.2 kg, and Barbara’s is 51.9 kg. He is standing on the x axis at xJ = +9.99 m, while she is standing on the x axis at xB = +3.27 m. They switch positions. How far and in which direction does their center of mass move as a result of the switch?

Answers

Answer:

the center of gravity moves by 1.9 m towards the origin

Explanation:

from the question we are given the following

John's mass (Mj) = 91.2 kg

Barbara's mass (Mb) = 51.9 kg

John's location (Xj) = + 9.99 m

Barbara's location (Xb) = +3.27 m

center of mass (X) = ?

the center of mass is where the masses of John and Barbara is concentrated, and it is given by the formula below

X = ( ( Mj x Xj ) + ( Mb x Xb ) ) / (Mj + Mb)

X = ( ( 91.2 x 9.99 ) + ( 51.9 x 3.27 ) ) / ( 91.2 + 51.9 )

X = 7.6 m

now when they switch positions their locations now become

John's location (Xj) = + 3.27 m

Barbara's location (Xb) = +9.99 m

now putting their new locations into the formula

X = ( ( 91.2 x 3.27 ) + ( 51.9 x 9.99 ) ) / ( 91.2 + 51.9 )

X = 5.7 m

therefore the center of mass moves by

7.6 - 5.7 = 1.9 m

the center of gravity moves by 1.9 m towards the origin
