Answer:
Your average speed is 60 kilometers per hour
Explanation:
240 divided by 4 is 60
240/4=60
Answer:
Explanation:
Energy stored in a capacitor
= 1/2 CV²
C is capacitance and V is potential of the capacitor .
When capacitor is charged to 24 V ,
E₁ = 1/2 x 2.4 x 24 x24 = 691.2 J
When it is charged to 12 volt
E₂ = 1/2 CV²
.5 X 2.4 X 12 X12
= 172.8 J
1). The "Opera" at 90.5 MHz has lower frequency,
so its wavelength is longer.
2). Whichever station is transmitting with higher power
has waves with higher energy.
Each photon of the transmission at 107.1 MHz carries more energy,
because the energy of a photon is proportional to its frequency.
But it's a mistake to think that the station at higher frequency has
waves with higher energy.
Answer:
A. The period of an oscillation does not depend upon amplitude.
Explanation:
The period of a spring-mass system is:
T = 1/f = 2π√(m/k)
where f is the frequency, m is the mass, and k is the spring constant.
The answer isn't B. There are no frictionless systems in the real world.
The answer isn't C or D. As shown, the frequency is a function of both the mass and the spring constant.
The answer isn't E. Turning motion into heat is not an advantage for a clock.
The correct answer is A. The period of the system does not depend on the amplitude.
Answer:
10 newtons
Explanation: 10 of the 20 cancels out and the other 10 is force.
