Answer:
a = 0.50 m/s²
v = 6.0 m/s
Explanation:
Step 1: Given data
- Initial velocity (u): 0 m/s (rest)
- Displacement of the marble (s): 36 m
Step 2: Calculate the acceleration
We will use the following suvat equation.
s = u × t + 1/2 × a × t²
s = 0 × 12.0 s + 1/2 × a × (12.0 s)²
36 m = a × 72.0 s²
a = 0.50 m/s²
Step 3: Calculate the final velocity
We will use the following suvat equation.
v = u + a × t
v = 0 + 0.50 m/s² × 12.0 s
v = 6.0 m/s
Answer:
a. It extends to about 100,000 times the distance between the Earth and the Sun.
d. Stars are born from clouds of gas and dust, and when they die they return gas and dust to the galaxy from which new stars can be born.
b. Kind of interesting
Explanation:
- The average distance between the sun and the earth is called one astronomical unit.
- It is the unit of length to measure the distance in our solar system.
- It is equal to 1.49 x 10¹¹ m
- It is analogous to the light-year to measure the distance of distant stars.
- So according to this unit, our solar system extends about 100,000 times the distance between the Earth and the Sun.
False. Heat radiation from the sun cannot reach Earth, we cannot receive TV or GPS signals from satellites, and we cannot detect the light from distant stars.
Oh, wait . . .
Conrad’s physician has determined that the damaged that causes
his change of behavior is the amygdala. The amygdala is the gray matter of the
cerebral hemisphere in which is responsible for making an individual have
emotions for it is the emotional center. Thus, it makes Conrad changed because
this could have been damaged, making his behavior to change.
