The angle that the boat must follow for it to be able to head upstream successfully should be 45 degrees from the current at which it is crossing. This is exact protocol that is done or learned by rescuers. In able to swim across a current, you must not invest your energy in heading towards it but rather move in a semi-perpendicular direction from it.
Answer:
PEgrav = m *• g • h
Explanation:
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.

The charge transported as a result of charging is 43200C .
we can note the following data from the statement :
Current (i) = 3A
Time interval (t) = 4 hrs = 14400secs
As we know ,
Current is defined as the rate of flow of the charges between two points when a potential difference is applied between them.
Mathematically , it can be written as
Current(i) = charge (q)/ time(t)
Q = i × t
= 3 × 14400
= 43200 C
By dividing the value of the current passed through the circuit by the time for which the charge is passed gives out the value of the charge passed .

Answer:
Explanation:
They found that an impact on the near, hotter side of the moon would form a crater about two times larger than craters formed by a similarly sized asteroid on the cold, far side of the moon. A new study suggests that the side of the moon that faces Earth (left) plays host to larger basins than the far side (right) because of the crust's composition.
