Hey there!
Option A
A climate crisis is occurring in California where sudden forest fires occur due to this .
"700 watts" means 700 joules of work per second.
"300 watts" means 300 joules of work per second.
If the labels on both machines are true, and both machines
are loaded to their full capacity, then the 700-watt engine
is doing work faster than the 300-watt one.
The amount of energy the Sun radiates into space and the amount of energy that reaches Earth.
Explanation:
A boat at sea is being moved by the ocean current at 5 metres/minute directly to the east.
At the same time, it is being moved directly to the north at 3 metres/minute by a strong wind.
We need to find the magnitude and direction of the boat's overall velocity.
As both velocities are moving perpendicular to each other. The resultant velocity is given by :

For direction,

Hence, this is the required solutin.
