To develop this problem it is necessary to apply the concepts related to the Frequency according to the Period. Frequency is the number of repetitions per unit of time of any periodic event. The period is the length of time of each repetitive event, so the period is the reciprocal of the frequency.
The frequency of the metronome in seconds would then be
Since the frequency is inversely proportional to the period then
The correct answer is B. 375ms
Let's use the given equation, F = ma, to find out the force of each of the objects given.
A) F = 5 x 10 = 50 N
B) F = 5 x 20 = 100 N
C) F = 20 x 4 = 80 N
D) F = 20 x 3 = 60 N
The object with the greatest force is object B, with a force of 100 N.
Hope this helps! :)
The molecules of ice stick together in the process of cohesion. They are tightly packed so there isn't much room to move. Liquid water is a looser hold. The molecules can go past one another, and they will take the shape of whatever container they occupy. Water vapor is loosely contained, and it will will fill whatever container it is kept in, and it will take its shape, too.
Answer:The net force acting on the car is 3×103 Newtons
Explanation:
Answer:
a) 
Explanation:
a) the cross-sectional area of the hose would be the square of radius times pi. And since the sectional radius is half of its diameter d. We can express the cross-sectional area A1 in term of diameter d1
