A kettle consumes 198 kJ to boil water. If 168 kJ was used to boil the
water, what is the efficiency of the kettle?

Answers

The efficiency of the kettle is 117.9%

What is efficiency?

Efficiency is used to measuring how much work or energy we can conserve in a process. In other words, it is like comparing the output of the energy to the input of the energy in any given system.

It is also define as the ratio of  Energy Input to the Energy Output. To express it in percent multiply it by 100.

Here, Efficiency = Energy output / Energy input

          [tex]η =\frac{W_{out} }{W_{in} } * 100[/tex]

[tex]η = \frac{198kJ}{168kJ} * 100[/tex]

Against the park ranger's advice, a visitor at a national park throws a stone horizontally off the edge of a 83 m high cliff and it lands a distance of 93 m from the edge of the cliff, narrowly missing a visitor below.
What was the initial horizontal velocity of the rock, in m/s? You can round your answer to the hundredths place and use g ≈ 10 m/s2.

Answers

Answer:

20.37m/s

Explanation:

For this problem, we'll need a basic kinematic equation for both directions


Vertical direction:

[tex]y(t)=\frac{1}{2}a_{y}t^{2}+v_{o_y}t+y_{o}[/tex]

Knowing that the acceleration in the y-direction is due to gravity, and is constant near the surface of the Earth, where the rock is being thrown, we get [tex]a_{y}=g=-10m/s^{2}[/tex].  We're also given that the initial vertical height is 83m, so [tex]y_o=83m[/tex].  Additionally, we're given that the stone is thrown horizontally, and thus initially, it has no vertical velocity.  Only velocity in the x-direction.  Thus, [tex]v_{o_y}=0m/s[/tex].  Substituting known values into our equation:

[tex]y(t)=\frac{1}{2}(-10)t^{2}+(0)t+(83)[/tex]

[tex]y(t)=-5t^{2}+83[/tex]

This equation is true for all times until the acceleration changes (isn't constant... i.e. when it hits the ground).

What now?

We want to find the specific time when it does hit the ground.  Why?  Because this is the point in time where we know some extra information about what is happening in the x direction, and that will help us deal with the x-direction equation.  

When the stone does hit the ground, the output of this function (measuring the height of the stone) is zero, which leaves only one unknown value, t... the time associated with that y:  the time that it takes to hit the ground:

[tex]0=-5(t_{ground})^{2}+83\\-83=-5(t_{ground})^{2}\\\frac{-83}{-5}=(t_{ground})^{2}\\16.6=(t_{ground})^{2}\\\sqrt{16.6}=\sqrt{(t_{ground})^2}\\4.074309757seconds=t_{ground}[/tex]

Again, this is the time that the stone hits the ground.  Knowing how special this time is, one might give it a special subscript to keep track of it.  

[tex]t_{ground}=4.074309757seconds[/tex]

Horizontal direction

Reusing the basic kinematic equation for the horizontal direction:

[tex]x(t)=\frac{1}{2}a_{x}t^{2}+v_{o_x}t+x_{o}[/tex]

Note that in the horizontal direction, there is no acceleration (after the rock is released), so [tex]a_{x}=0[/tex].  Also, if we define the base of the cliff as our origin, then at the top of the cliff where the rock is released, the initial x-position is still zero, aka, [tex]x_{o}=0[/tex]

[tex]x(t)=\frac{1}{2}(0)t^{2}+v_{o_x}t+(0)\\x(t)=v_{o_x}t[/tex]

While we don't know the initial horizontal velocity, we do know an output of the function for one specific input... we know that when the stone hits the ground, that the stone's horizontal distance is 93m from the cliff.  So, if we input [tex]t_{ground}[/tex] into this function, it will give an output of 93.  The only remaining unknown is the initial velocity in the x direction.  One equation, one unknown, we can solve this:

[tex]x(t_{ground})=v_{o_x}t_{ground}\\83=v_{o_x}(4.074309757)\\\frac{83}{4.074309757} =v_{o_x}\\20.37154879m/s =v_{o_x}\\[/tex]

If there were a component of initial velocity in the y direction, we would need to use the Pythagorean theorem to combine them.  However, as the initial y component of velocity is zero, the initial velocity is simply the initial x velocity.

Paying attention to directions, round to the answer to the nearest hundredth:

[tex]20.37m/s =v_{o}\\[/tex]

Explanation:

How does radioactive decay work? Radioactive decay is a process by which unstable nuclei become more stable through the emission of alpha or beta particles or gamma rays.

Since a half-life is the time taken for half of the isotopes to decay, we can simply divide the initial mass of 100 grams by 2; this gives us 50 grams.

a. Calculate the resistance of the unknown resistor.


b. Draw the circuit and label each component.

Answers

The resistance of the unknown resistor is determined as 0.39 ohms.

Equivalent resistance of the circuit

The total resistance of the circuit is calculated as follows;

V = IR

R = V/I

R = (3.5)/10

R = 0.35 ohms

The resistors are in parallel arrangement

1/R = 1/R₁ + 1/R₂ + 1/R₃

1/0.35 = 1/5 + 1/10 + 1/R₃

100/35 = 3/10 +  1/R₃

20/7 = 3/10 +  1/R₃

if a volume of air is warmed it expands due to increased translational kinetic energy as it expands it will start to cool.

When does temperature increase volume?

We can then conclude that at constant pressure, temperature and volume are directly proportional: temperature increases, volume increases; decrease temperature, decrease volume.

In this case, the higher the temperature, the greater the kinetic energy that acts on the molecules of this gas, so when the gas expands, these molecules find more space and collide less, which will cause the gas to cool.

A car is moving at a rate of 72km/hr . How far does the car move when it stops after 4 seconds?

step by step asap pls​

Answers

Answer:

The car will stop after 4 seconds after moving the distance of 0.08km.

Explanation:

The reading above it clearly states that a car is moving at a speed of 72Km/hr. And it asking for the distance the car move when it stops after 4 seconds.

Looking at speed formula , speed=distance÷time.

But in this problem we I finding distance, so in speed formula make distance the subject.

Therefore distance = speed × time

Before going ahead you should have this in mind the unit for distance is Km and m . Our speed is in Km/hr but our time is in second. In this case change 4 seconds to hour which is 0.00111 hr .you change second to hour because hr will cancel hr when solving for distance giving distance unit Km

Distance = speed × time

Distance= 72km/hr × 0.00111 hr

hour cancel hour

Distance= 72km × 0.00111

Distance = 0.08km

Therefore the car will stop after 4 seconds after moving the distance of 0.08km.

Please mark brainliest.

conversion :

72 km/h = 72 × (1000/3600) = 20 m/s

so, in 4 seconds it travel

4 × 20 = 80 meters = 0.08 km
