Choice-A is the correct one. It doesn't say it, but it means he'll see the ball reach the catcher's mitt first BEFORE HE HEARS IT slap the mitt.
I don't understand this question
Answer:
the four seasons would each be twice as long as they are now
Explanation:
A year is the result of the Earths revolution around the sun i.e., the Earth takes 365 days to complete one revolution around the sun. A day is the result of the Earth's rotation on its axis i.e., it takes 24 hours for Earth to complete one rotation on its axis.
The Earth is titled by about 23.5 degrees, this results in the seasons of Earth. The distance from the sun has nothing to do with the seasons. During the northern hemisphere winter the Earth is actually closer to the sun than in the summer. So, if our year was twice as long then the seasons would be twice as long.
Explanation:
It is given that,
An electric dipole consists of charges +2e and -2e separated by 0.82 nm
Charge, 
Distance between charges, 
Electric field strength, 
(a) The magnitude of the torque on the dipole is given by :
When dipole moment is parallel to the electric field, 
(b) When the dipole is perpendicular to the electric field, 
(Since, p = q × d)
(c) When the dipole moment is anti parallel to the electric field, 
Since, 
Hence, this is the required solution.
