Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.
Answer:
For the first situation, we first need to find the mass of the second train car.
In order to do that, we apply the conservation of the amount of movement:
and we have as a result:
m2 = 289.6875
For the second situation, also we will apply the conservation of the amount of movement:
and we have as a result:
V = 2.64 (it is moving to the right)
Answer:
B, C, F
Explanation:
Conduction is heat transfer by means of molecular agitation within a material without any motion of the material as a whole. If one end of a metal rod is at a higher temperature, then energy will be transferred down the rod toward the colder end because the higher speed particles will collide with the slower ones with a net transfer of energy to the slower ones.
I would provide the source, but this is not allowed as it seems the website does not encourage learning of well-established materials.
Let me know if you require a further explanation
the force of gravity on planet a is g = 5.72 m/s2
There is an object that weighs 12 kg. The object's weight on Planet A is 69 N. The equation F=mg, where F is the weight, m is the mass, and g is the force of gravity, can be used to calculate the force of gravity on Planet A:
g = F/m
g = 69 N/ 12 kg
g = 5.72 m/s2
<h3>What is the gravity force?</h3>
The force of attraction between any two objects in the universe is known as gravity or gravitational force. The mass of the object and the square of the distance between them determine the force of attraction. The weakest known force in nature, it is by far.

A radio station broadcast on a frequency of 3.7 mhz what is the energy of the radio wave A radio station broadcasts its programmes at a wavelength of 500 m. Find the frequency of the radiowaves transmitted by the radio station, if the speed of radiowaves in air is 3 x 108 m/s. Ans: 6 x 10 Hz
<h3>What is
radio station ?</h3>
Radio broadcasting is the act of sending audio (sound), occasionally together with accompanying metadata, across radio waves to radio receivers used by the general public. Unlike satellite radio, which uses a satellite in Earth's orbit, terrestrial radio broadcasting uses a land-based radio station to transmit radio waves. The listener needs a broadcast radio receiver to hear the material (radio). A radio network with which stations frequently have affiliations provide content in a standard radio format, whether through broadcast syndication, simulcasting, or both. Radio stations use a variety of modulations to transmit their signals, including FM (frequency modulation), which is an older analog audio standard, and AM (amplitude modulation).
