Explain why it is esaier to climb a mountain on a zigzag path rather than one straight up the side. is your increase in gravitat

ional energy the same in both cases?
Physics

Answer:

More work done with less power

The increase in gravitational energy is the same as the height which is a function of gravitational energy is the same in both cases

Explanation:

Climbing the mountain in zigzag pattern is easier because

1. The time it takes to climb increases so that the required power or rate of doing work decreases

2. Climbing in zigzag pattern affords the use of leverages by the sides

3. Similar mechanical power gain and efficiency from using a drive screw instead of a nail to fasten items together can be achieved

The increase in gravitational energy is the same gravitational energy ~ mass × gravity ×height

Gibbons, small Asian apes, move by brachiation, swinging below a handhold to move forward to the next handhold. A 9.0 kg gibbon
LiRa [457]

Answer:

241.8 N.

Explanation:

The force on branch provides a reaction to the ape's weight force plus the centripetal force needed to keep the gibbon in a circular motion of radius 0.60 m.

Centripetal force = mv^2/r

F = mg + mv²/r

F = m(g + v²/r)

where,

m = mass

= 9 kg

g = acceleration due to gravity

= 9.8 m/s²

v = 3.2 m/s

r = 0.60 m

F = 9 * (9.8 + 3.2²/0.60)

= 241.8 N.

Is a projectile motion graph a straight graph or a curved graph<br>​
Usimov [2.4K]

Answer:

» Projectile motion is a curved graph.

☑ This is because projectile motion consists of both vertical and horizontal motion, with one starting angle. Hence as the body starts motion, it is acted upon by gravity.

At point v = 0, the motion is free from gravity hence approaching horizontal motion.

Examples;

  • A ball kicked upwards at an angle which is not 90°
  • A man playing golf.
  • A plane dropping a bomb.

A vehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning of
attashe74 [19]

Answer:

Technician A is correct

Explanation:

The best approach to solve the problem is that of technician A. using a fluorescent die is the easiest and most efficient way to trace leaks with unknown sources. The fluorescent die will simply illuminate the path to the leaking spot in the engine of the car, without any need for much speculations. This makes this method a sure approach.

However, Technician B's approach still has a lot of assumptions factored into the methodology, and would not work properly. It will still require the painstaking attempts trying to make guesses where the oil leak is coming from, which will lead to wastage of time and energy.

This makes Technician A have the right approach to solving the problem
