If this Answer helped, please mark it as Brainliest. Thank you!
You find the answer by solving the problem.
You can solve the problem by using the equation that tells how force, mass, and acceleration are connected.
The equation is in the "Hint".
F = m • a
Force = mass • acceleration
mass = 200 kg
acceleration = 2 m/s^2
Force = (2000 kg) • (2 m/s^2)
Force = 400 Newtons

A. The probable direction of storm movement for the next 12 hours.
Answer:
A. The probable direction of storm movement for the next 12 hours.
Explanation:
In the northern hemisphere, air circulation is counterclockwise around a low pressure system. The arrow drawn on the diagram is below (south of) the center of low pressure, so the winds will be to the east in that area. The arrow is pointed in the direction of probable frontal system movement.
__
Other answer choices:
The map is of a portion of the eastern part of the North American continent. There is no ocean in the area of the frontal system or the arrow, so ocean currents are irrelevant to what the arrow is showing.
Convection currents in the atmosphere are vertical air currents. The horizontal arrow cannot show anything about convection currents.
Due to jet stream and trade wind direction over North America, the storm system shown would have originated farther to the north and west. The arrow points to the east northeast, so is not pointing in the direction of the origin of the storm system.
