Mr. Claspell moves 100 N of avocados straight up 2.0 meters.
solniwko [45]

Answer:

see the various answers below

Explanation:

From the given details, we can see that we are required to solve for the work done.

1. Mr. Claspell moves 100 N of avocados straight up 2.0 meters.

Work done= Force*Distance

Work done= 100*2= 200Joules

2. The Flash tackles the Reverse-Flash and pushes him 3.0 meters using a force of 200 N.

Work done= Force*Distance

Work done= 200*3= 600Joules

3. Darth Vader moves a large rock using force. That force is 3.0 N and he moves the rock 15 meters.

Work done= Force*Distance

Work done= 3*15= 45Joules

4. Mario carries Princess Peach 45 meters away from Bowser’s Castle with a force of 5.0 N

Work done= Force*Distance

Work done= 5*45= 225Joules

5. A roller coaster car lifts a group of people 50 m to the top of the roller coaster with a force of 550 N.

Work done= Force*Distance

Work done= 550*50=27500Joules or 27.5kJ

A runner has a temperature of 40°c and is giving off heat at the rate of 50cal/s (a) What is the rate of heat loss in watts? (b)
Andrew [12]

Answer:

(a)  209 Watt

(b) 4482.8 seconds

Explanation:

(a) P = 50×4.18

Where P = rate of heat loss in watt

    P = 209 Watt

Applying,

Q = cm(t₁-t₂)................ Equation 1

Where Q = amount of heat given off, c = specific heat capacity capacity of human, m = mass of the person, t₁ and t₂ = initial and final temperature.

From the question,

Given: m = 90 kg, t₁ = 40°C, t₂ = 37°C

Constant: c = 3470 J/kg.K

Substtut these values into equation 1

Q = 90×3470(40-37)

Q = 936900 J

But,

P = Q/t.............. Equation 2

Where t = time

t = Q/P............ Equation 3

Given: P = 209 Watt, Q = 936900

Substitute into equation 3

t = 936900/209

t = 4482.8 seconds

Does potassium have a greater nuclear charge than Chlorine?
valentinak56 [21]

Answer:

This is important because in the case of the potassium atom, the outermost electrons will be attracted by the nucleus more. In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons.
