Answer:
Increase
Explanation:
Energy of given as follows
E = h f
Where f is the frequency of incident light
when high frequency light falls then it will increase the number of produce photon and that increase in number of photon will lead to increase in the number of electron.When number of electron will increase it mean that current will also increase.
So we can say that when frequency increase then current will increase.
Answer:
Ben's average speed was twice Debby's average speed.
Explanation:
Ben covered a total distance of 16 miles (10+4+2) and Debby covered 8 miles (3+2+2+1) which is half of what Ben covered. As they both reached the place in the same amount of time it tells us Ben was faster.
Answer:
1000m/s²
Explanation:
Given parameters:
Initial velocity = 6000m/s
Final velocity = 11000m/s
Time = 50s
Unknown:
Acceleration of the plane = ?
Solution:
Acceleration is the rate of change of velocity with time:
Acceleration = (final velocity - starting velocity) ÷ time
Therefore;
Acceleration = 
= 1000m/s²
Answer:
1.) Fan Speed was manipulated
2.) The acceleration was measured
Explanation:
Answer: Temperature is the average kinetic energy of the molecules (how hot or cold something feels). Heat energy is the energy created y the motion of the molecules in an object. Heat flows from hot body to cold body. Temperature rises when heated and falls down when an object is cooled down.
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale. Each of these scales uses a different set of divisions based on different reference points, as described in detail below.
