You can conclude that the force of static friction acting on the boxcar is equal to 200N while you're pushing on it.
Answer:
Since heated materials give off infrared radiation, the warm greenhouse soil, water, sand and other materials emanate this thermal radiation in longer wavelengths than the radiation that heated the materials. A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth. Less heat radiates into space, and Earth is warmer.

Drag
Explanation:
The shape of a particle affects its drag.
The drag on a body is the a force that tends to halt the motion of a particle in a fluid such as air or liquid.
- The shape and build of a body affects the drag of the body.
- This is why fishes evolved a torpedo streamlined shape in water to help them have less drag and swim faster.
- Airplane are specially built to avoid drag of air when they are flying.

Answer:
Magnitude of the resultant = 357.85 N
Direction of the resultant is 12.1° from the 220 N force and still in between the two forces 150 N and 220 N
Explanation:
Let the direction in which the 220 N force is acting be the x-axis, then the 150 N force is acting 30° from the 220 N force, i.e. the x-axis.
The 220 N force in vector form = (220cos 0°)î + (220sin 0°)j = (220î) N
The 150 N force in vector form = (150cos 30°)î + (150sin 30°)j = (129.9î + 75j) N
The resultant is the vector sum of both forces = (220î) + (129.9î + 75j) = (349.9î + 75j)
Magnitude = √(349.9² + 75²) = 357.85 N
Direction = tan⁻¹ (75/349.9) = 12.1° From the 220 N force (x-axis)
