Answer:
v = 6.72 m/s
Explanation:
Given that,
Vertical height, h = 2.31 m
We need to find the speed at the bottom of the slide. Let the speed be v. We can find it using the conservation of energy such that,
Put all the values,
So, her speed at the bottom of the slide is equal to 6.72 m/s.
Electrons are added to your body as you shuffle your feet across the room. Then the shock is when they discharge from your body to the doorknob when you touch it.
Answer:
C. Newton's First Law of Motion
Explanation:
As the car comes to an abrupt stop, the body is still moving forward, and is moved back by the seatbelt, an outside force. If not for the seatbelt, the body would continue forward until acted on by the car itself, or thrown out of the car.
<u>Complete Question:</u>
Which words or phrases describe the outer planets? Check all that apply.
1. rocky
2. gaseous
3. few moons
4. low density
5. slow rotation
<u>Answer:</u>
The outer planets of our Solar System are primarily composed of gases, dust, being bigger in size but have lower density as compared to the inner planets.
<u>Explanation:</u>
According to the observation and data received by the the astronomical entities worldwide, it's concluded that the outer planets of our Solar System; Jupitor, Satern, Uranus and Neptune.
These planets are also termed as Jovian planets or Gas Giants as they are primarily made of gases and dust. However, their inner core is made of solid heavy metals. Jupitor is the largest among all of them, having 63 so far identified moons. Its atmosphere is stormy.
Talking about the density, since these planets are made of dust particles and gases, they are of lower density. Uranus has the smallest mass inspite of being the bigger planets of the Solar System. This is because these planets have nothing or nearly nothing solid.
Answer:
Explanation:
Using the Gauss Law, we obtain the electric Field for a uniform large line of charge:
We calculate the potential difference from the electric field:
