A 92.6 kg weight-watcher wishes to climb a mountain to work off the equivalent of a large piece of chocolate cake rated at 735 (food) Calories. How high must the person climb? The acceleration due to gravity is 9.8 m/s 2 and 1 food Calorie is 103 calories. Answer in units of km.
Answers
Answer:
349 m
Explanation:
Parameters given:
Mass of climber, m = 92.6 kg
Amount of food calories = 735
1 food calorie = 103 calories
735 food calories = 75705 calories
1 joule is equal to 0.239 calories. Therefore, 75705 calories will be 316749.72 joules.
Hence, this is the amount of work the climber must do work off the food he ate.
Work done is given as:
W = Force * distance
W = m * g * h
h = W/(m * g)
h = 316749.72/(92.6 * 9.8)
h = 349 m

The first step in problemsolving is identifying problem. The correct option is c.
What is problem solving?
Problemsolving, which is a common part of most activities, is the process of achieving a goal by overcoming obstacles.
Problems that require resolution range from simple personal tasks to complex issues in business and technology.
7 Steps can be followed to allow the problem solving success
- Step 1: Identifying the Problem.
- Step2: Establishing Objectives.
- Step three is brainstorming.
- Step 4: Evaluate Alternatives
- Step 5: Selecting a Solution
- Step 6: Active Implementation of the Selected Solution
- Step 7 is an evaluation.
Fearless problem solvers share five key characteristics: they are unafraid, optimistic, driven, smart, and empathetic.
Thus, the correct option is c, i.e., identifying the problem.

As the runner was travelling for 9 seconds, he covered a distance of 99.9 metres. 9 seconds x 9 seconds = 81 seconds squared, and the runner covers roughly 1.23 metres in distance every second squared.
Explanation:
Acceleration=
Time
FinalVelocity−InitialVelocity
Therefore:
\begin{gathered}Acceleration=\frac { 11.1\quad m/s\quad -\quad 0\quad m/s }{ 9\quad seconds } \\ \\ =\frac { 11.1\quad m/s }{ 9\quad seconds } \\ \\ =1.23\quad m/{ s }^{ 2 }\quad (2\quad decimal\quad places)\end{gathered}
Acceleration=

water are found to have decreased.
Name and describe the process that causes the decrease in the volume of the water, and
explain why the temperature of the water decreases.
Answers
Answer: Evaporation and heat loss to the surrounding.
Explanation:
The process is known as evaporation.
Evaporation takes place at any temperature but increases with increase in temperature. The molecules of water evaporate, that is, escape into the atmosphere thereby causing the volume of water to reduce.
The temperature decreases due to heat loss from the water into the surrounding. This will cause the temperature of the water to drop.
b. trough.
c. crest.
d. wavelength
Answers
The highest point of a wave is called the "crest." A wave is a disturbance that travels through a medium or space, transferring energy without transporting matter. Therefore, the correct answer is option c.
As a wave propagates, it undergoes cycles of oscillation with alternating high and low points. The highest point of a wave, where the displacement or amplitude is at its maximum, is referred to as the "crest." On the other hand, the term "trough" refers to the lowest point of a wave, where the displacement or amplitude is at its minimum in the negative direction. The trough is the opposite of the crest, representing the bottommost part of a wave.
