A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. Transformers are mainly used to increase or decrease voltage in power lines or electric power applications. So your answer would be D. transformer
1000 m/s
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Answer:
The total momentum of the universe is always the same and is equal to zero. The total momentum of an isolated system never changes. Momentum can be transferred from one body to another.
Momentum quantifies how likely an object is to stay in motion. Momentum can also be explained using the equation, p=mv, where p is equal to momentum, m is equal to mass, and v is equal to velocity.
Explanation:
Answer:
The maximum height of the ball will be "16.53 m".
Explanation:
Given that,
As we know,
The initial as well the final height on the ball will be same after it reaches it's maximum height.
then,
⇒
where,
hence,
The max height of the ball will be:
⇒
An advantage to having a computer is it has fast and easy access to many resources, research articles, news sources, reading material, and activities. A disadvantage is being on the computer too much isn’t good people will spend their whole day playing videos games instead of learning.
