<span>Venus goes around faster than Earth, so its period must be less than Earths 1.0 years. That eliminates the first two answers. My recollection is that T^2 = k r^3, relating period of orbit to radius, so T should be (0.72/1.00)^3/2 = 0.61 of the Earths period, so 0.62 is ans. </span>
Answer:
True
Explanation:
As per a survey conducted in the United States, it has been highlighted that among 30 million children participating in any sports, there are 3.5 million children who face injuries. It is because of these injuries that the children have to take some leave or absence from the sports. Also, the statistics discloses the fact that among all the injuries faced by the humans, one third of them are related to the childhood sports activities. Sprains and strains are among the most common of the injuries.
Answer:
Explanation:
Given data
Ex = Ey = 0
Ez=(4.3V/m)cos(π×10¹⁵s⁻¹)(t-x/c)
To find
The amplitude of the magnetic field component
Solution
The electric field is given by:
Ez=(4.3V/m)cos(π×10¹⁵s⁻¹)(t-x/c)
Where Em=4.3 V/m
The magnitude of magnetic field is given by:
Where Em is amplitude of electric field and c is speed of light.
Substitute the given values
So
The correct answer for the mean would be 8
I hope that this helps !
Answer:
F/2
Explanation:
In the first case, the two charges are Q1 and Q2 and the distance between them is r. K is the Coulomb's constant
Hence;
F= KQ1Q2/r^2 ------(1)
Where the charge on Q1 is doubled and the distance separating the charges is also doubled;
F= K2Q1 Q2/(2r)^2
F2= 2KQ1Q2/4r^2 ----(2)
F2= F/2
Comparing (1) and (2)
The magnitude of force acting on each of the two particles is;
F= F/2
