Answer:
Speed= 10meters per second, Frequency = 4hz
Explanation:
First we need to find the frequency of the wave. The formula for frequency is: f (frequency) = 1 / T (period). This means we need to convert the period into seconds and then use it as a denominator with one on the numerator.
Since the period is 0.25,
1/0.25= 4hz
Now, we just need to multiply the frequency with the wavelength
4hzx2.5= 10
= 10 meters per second
Answer:
Explanation:
the sphere is solid and conducting, so the charge is uniformly distributed over its volume.
Answer:
12,740 N
Explanation:
The weight of the hyppogriff is given by:
where
m = 1300 kg is the hippogriff's mass
g = 9.8 m/s^2 is the acceleration due to gravity
Substituting the numbers into the equation, we get:
F=ma, approximating that gravity is 10 m/s
F=6*10
F=60
