Answer: The period of the pendulum will increase. Because of less gravity
Explanation:
Since the force of gravity is less on the Moon, the pendulum would swing slower at the same length and angle and its frequency would be less. Hence more time period will be experienced by the pendulum. On the moon, the acceleration due to gravity g is less when compared to that of the earth.
Although X-rays have many benefits, they can be dangerous to human health because they are short wavelength, high frequency, with photons sufficiently energetic to damage DNA molecules.
B is false.
not all carbon atoms have 6 neutrons. Carbon 13 for example has 7 neutrons
Answer:
This is what they said in english if everyone was wondering
Explanation:
determine the value of the velocity carried by a body whose mass is 3kg and its kinetic energy is 400Joule
For each revolution, the satellite covers the circumference
of its orbit.
The circumference of a circle is (pi) x (diameter).
Since the satellite is 22,500 miles from the center, that number
is the radius of the circle. The diameter is 45,000 miles.
The circumference is (pi) x (45,000 miles) = 141,372 miles
The satellite's average speed is 141,372 miles per day, or
(141,372 / 24) = 5,890 miles per hour
relative to the center of the Earth.
