1) Mass won't change (59 kg).

2) W_{TM}=mg_{_{TM}}\medskip\\m=\dfrac{W_{TM}}{g_{_{TM}}}\medskip\\W_{E}=mg_{_E}=W_{TM}\dfrac{g_{_E}}{g_{_{TM}}}=20\times \dfrac{9.08}{1.62}\approx 112.0988

3) W_{TM}=mg_{_{TM}}=100\times 1.62=162

4) mg_{_{object}}=G\dfrac{M_{object}m}{r^2}\medskip\\g_{_{object}}=G\dfrac{M_{object}}{r^2}

As G and r are constants, g_{_{object}}\propto M_{object}. In other words, the more massive the object is, the bigger its gravitational acceleration (obviously, the lighter the object is, the lesser its gravitational acceleration)

A rotating fan completes 1200 revolutions every minute. consider the tip of a blade, at a radius of 0.19 m. through what distanc
ser-zykov [4K]

The tip of the fan moves through the outer side of the circle.

So it moves a distance of perimeter of circle in one revolution.

Perimeter of circle = 2\pir, where r is the radius of circle.

In this case radius of circular motion = 0.19 meter

So perimeter of circle = 2\pi*0.19 = 0.38\pi = 1.194 m

So distance does the tip move in one revolution = 1.194 meter

The voltage V in a simple electrical circuit is slowly decreasing as the battery wears out. The resistance R is slowly increasin
Ganezh [65]

Answer:

The current in the circuit decrease slowly .

Explanation:

Given as :

For the electrical circuit

The voltage V in the circuit is slowly decreasing

The resistance R of the resistor slowly increasing after heating

Now, From Ohm's Law

Voltage is directly proportional to the flow of current through circuit

I.e V ∝ I

Or. V = R × I

where R is the proportionate constant and this is the resistance of the resistor

whose property is to opposes the flow of current in the circuit

So, If R value more then current I reduces in the circuit

∵ Here in the circuit ,  The resistance is slowly increasing, so, current I is slowly decreasing .

Hence The current in the circuit decrease slowly . answer

1. You wish to heat 20 kg of water from 40°C to 80°C. How many kcal of heat are necessary to do this? To how many kJ does this c
adelina 88 [10]

Answer:

<h2>3,343.68kJ </h2>

Explanation:

Heat energy used up can be calculated using the formula:

H = mcΔt

m = mass oof the object (in kg) = 20kg

c = specific heat capacity of water = 4179.6J/kg°C

Δt change in temperature = 80-40 = 40°C

H= 20* 4179.6 * 40

H = 3,343,680Joules

H = 3,343.68kJ
