Questions in physics

[Terjawab] How do I determine which object has the greatest acceleration?

[Terjawab] A stubborn 150 kg pig sits down and refuses to move. To drag the pig to the barn, the exasperated farmer ties a rope around the pig and pulls with his maximum force of 800 N. The coefficients of friction between the pig and the ground are [tex]\mu_s = 0.80[/tex] and [tex]\mu_k = 0.50[/tex]. Determine if the farmer can move the pig and calculate the force of friction acting on the pig.

[Terjawab] What is the loose covering of weathered rock particles and decaying organic matter overlying the bedrock of the Earth's surface?

[Terjawab] Which does NOT represent one of Koch’s postulates? A. Isolate germs from an infected animal. B. Grow germs in a lab culture. C. Inject germs into a healthy animal. D. Watch to determine how long it takes for the healthy animal to become ill.

[Terjawab] If you shine red light at a green plant and green light at another green plant, knowing that a plant must absorb light to grow, which plant will grow faster?

[Terjawab] A 1200 kg car moving at 25 m/s has the brakes applied with a deceleration of 8.0 m/s². How far does the car travel before it stops?

[Terjawab] A horizontal force of 200 N is applied to a 55 kg cart across a 10 m level surface. If the cart accelerates at [tex]2.0 \, \text{m/s}^2[/tex], what is the work done by the force of friction as it slows the motion of the cart?

[Terjawab] A person runs off a cliff into a lake below. If the person leaves the cliff with a horizontal velocity of 4 m/s, how far away from the cliff does he land if the cliff is 17 m high?

[Terjawab] What types of germs are found on hands?

[Terjawab] Find the weight of a 25 kg table. (Use [tex]g = 10 \, \text{m/s}^2[/tex])
