Answer:
The correct answer is -
B. The velocity would double (v = 2v).
C. The wavelength would be half (λ = λ/2).
Explanation:
A wave has a speed or velocity that is related to the wavelength of the wave and the frequency of the wave and this relationship can be represented by the following equation-
Wave velocity V = Wavelength (λ) * Frequency (f)
Frequency (f) = Velocity (V) / Wavelength(λ).
The frequency and wavelength are inversely proportional and frequency and velocity are directly proportional to each other.
So, if f = 2f then,
putting value in the formula,
2f = 2v/λ, which means, f = 2v and f = λ/2
when the frequency is doubled, the wavelength will be halved and velocity will be doubled.
Winds are the main cause of ocean currents in the ocean.
The kinetic energy of the object is 392 Joules.
I know you only need two, but here are some options to choose from.
Tip 1 - throwing a fastball. Use two points to keep your arm properly aligned your biceps brush your ear at the top of the backswing, and your pitching hand brushes your hip at release.
Tip 2 - throwing a curveball. Pictures should know that in order to maximize your curves, you should visualize a series of dots from the mound to the outside corner of the plate. Pitch along those dots.
Tip 3 - throwing a fast pitch rise. It’s possible that your wrist snap may be sideways. Play with different grips or finger pressures and try to relax them.
Tip 4 - throwing a change-up. Don’t always throw the change-up in a given situation. Make sure to change your pitch selection.
Tip 5 - throwing a drop-ball. Keep your pitching arm close to your body to avoid injury.
Answer: it means object initially possessed equal number of positive and negative charges.
Explanation:
Object looks uncharged when it's in neutral state. That's positive charge equals negative charge.
The moment the transfer of charges take place, one gains electron while the other loses electron.
The gainer of electron becomes negatively charged while the looser of electron becomes positively charged.
