Answer:
The sports Car can accelerate at 2 m/s².
Explanation:
Force:
Force is the push or pull on an object with mass that causes it to change velocity or to accelerate.
Force represents as a vector, which means it has both magnitude and direction.
Given:
Mass of car = 1500 kg
Force = 3000 Newtons
To Find:
Acceleration, = ?
Solution:
Formula:
Therefore, the sports Car can accelerate at 2 m/s².
At stp conditions (
), the speed of sound is
The sound wave moves by uniform motion, so we can use the basic relationship between space, time and velocity:
where S is the distance covered by the sound wave in a time t. In our problem, t=3.00 s, therefore the distance covered by the sound wave is
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.
Answer:
B. ) 0.34 m
I definitely guessed and got the right answer so :))
Answer:
Explanation:
The law of gravitation
Universal gravitational constant [S.I. units]
Mass of Earth [S.I. units]
Mass of a man in a spacecraft [S.I. units]
Earth radius [km]
Distance between man and the earth's surface
