0²=(7.8)²+2×9.8×s
s=60.84/19.6=3.1m she travel 3 .1m high.
weight=m×g=
Answer:
The average speed is 10,082
Explanation:
Do the formula
Distance * time = speed
2840 * 3.55
= 10,082
Answer
A. Yes, because they did several tests with the soccer balls and recorded their observations. B. Yes, because every student kicked
Explanation:
Answer: short wavelength, high frequency
Explanation:
Gamma rays are highly energetic electromagnetic waves. High energy implies high frequency.
E = h ν
h is the Planck's constant, ν is the frequency.
For electromagnetic radiation, frequency is inversely proportional to wavelength. Thus, gamma rays have high frequency but short wavelength.
The frequency of gamma rays is greater than 10¹⁹ Hz and wavelength is less 10⁻¹² m.
