Explanation:

Charlie runs 6.5 km/hr

-> Charlie wants to run for 1.5 hours

6.5km + 6.5km/2

= 6.5 km + 3.25km

= 9.75 km

Answer:

The correct option is;

Kinetic energy is least as you are moving from he highest point of the swing moving down to the lowest point of the swing

Explanation:

The formula for the kinetic energy, KE, is given by the following formula;

KE = 1/2 × m × v²

Where;

m = The mass of the body in the study

v = The velocity of motion of the body

Therefore, the kinetic energy increases with velocity and therefore, is lowest at the top of the swing when the object is still for a moment

The total mechanical energy of the body is given by the following equation;

Total mechanical energy, [tex]E_T[/tex] = PE + KE = Constant

Where;

PE = The potential energy of the body = Mass × Acceleration due to gravity × Height

Therefore, the potential energy is highest at the top of the motion and lowest at the lowest point, which gives;

The kinetic energy is lowest at the top of the motion and highest at the lowest point of the motion.

Answer:

We can define power as:

P = W/t

where W is work, and t is time.

And the work needed to climb a distance (we can assume that climb a set of stairs is equivalent to climbing a given height) is:

W = g*h*m

Where:

g = gravitational acceleration

h = height climbed

m = mass.

g and h are the same for Juan and his sister, and the only thing that changes is the mass

The work for Juan is:

Wj = g*h*M

And for his sister, that has half his

Wa = g*h*M/2.

Then the power for Juan, is:

Pj = Wj/t1 = (g*h*M)/t1

Where t1 is the time that Juan needs to climb the stairs.

And for Anna is:

Pa = Wa/t2 = (g*h*M/2)/t2

Where t2 is the time that Anna needs to climb the stairs:

We know that they have the same power, then:

Pj = Pa

(g*h*M)/t1 = (g*h*M/2)/t2

M/t1 = M/2*t2

t1 = 2*t2

This means that the time in which Juan climbs the stairs is twice the time that Anna needs to climb the stairs.

Explanation:

How should the student change the circuit to give negative values for current and potential difference?

Positive and Negative current can be seen when charging and discharging a device or when powering a load.

Negative current can also be achieved when current is allowed to flow in other direction.

If the direction of the current is changed, the voltage will read negative. Changing of power or battery terminals can make voltmetre to read negative.

The student can reverse the direction of current flow in a circuit to obtain the negative values for current and potential difference in the circuit.

To determine the negative current flow and potential difference in a circuit, we can consider following ways;

Thus, the negative values of current and potential difference is obtained by reversing the direction of current flow in a circuit.

The location in this diagram do the magnetic field lines show that the magnetic field is strongest is in C and wekeness in D.

The lines representing the magnetic field are closed, that is, they have no beginning or end. This can be observed when we place iron filings on a sheet of paper, over a bar magnet: the pattern of lines formed continues on the part of the paper that is on the magnet, closing.

In the region of the poles we see that the lines of magnetic induction are closer to each other, therefore, we consider that close to the poles the magnetic field is more intense. In this case it is stronger in C and weaker in D.

Answer:

A sea breeze describes a wind that blows from the ocean inland towards land. ... However, water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean. The warm air over the land will rise throughout the day, causing low pressure at the surface.

Answer:

C-Mass

Explanation:

Answer:

High pressure.

Explanation:

The symbol H indicates high pressure, while the symbol L indicates low pressure. Therefore, option C is correct.

A weather map is a map of the world or a portion of it that uses symbols to depict the weather conditions at a given time, including temperature, pressure, wind speed and direction, humidity, clouds, visibility, and type and amount of precipitation.

Different kinds of weather maps are used by meteorologists to display forecasts. Satellite, Doppler radar, precipitation, temperature, and wind speed are the primary weather maps. Let's investigate each of these in greater depth. There are four types of weather maps and that is station model map, aviation map, temperature map, and streamline map.

The symbol H indicates high pressure. Therefore, option C is correct.

The sample of fossilized wood is 22920 years old.

The half life is the time required for a substance to decay to half of its initial value. It is given by:

[tex]N=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} }[/tex]

Where N is the final value of the substance, No is the initial value of the substance, t is the time and [tex]t_\frac{1}{2}[/tex] is the half life.

Given a half live of 5730 years, N = 1.5g, No = 24g. Hence:

[tex]1.5=24(0.5)^\frac{t}{5730} \\\\1/16=(0.5)^\frac{t}{5730} \\\\ln(1/16)=\frac{t}{5730} ln(0.5)\\\\t=22920\ years[/tex]

Therefore the sample is 22920 years old.

Answer:

v' = 2.4 m/s

Explanation:

Given that,

Mass of one skater, m = 60 kg

Mass of the other's skater, m' = 60 kg

The two skaters push off each other. After the push, the smaller  skater has a velocity of 3.0 m/s.

When there is no external force acting on a system, the momentum remains conserved. It means initial momentum is equal to the final momentum. Let v' is the velocity of the larger skater.

mv = m'v'

[tex]v'=\dfrac{mv}{m'}\\\\v'=\dfrac{60\times 3}{75}\\\\v'=2.4\ m/s[/tex]

So, the velocity of the larger skater is 2.4 m/s.

Answer:

m = 100[gram]

Explanation:

In order to solve this problem, we must remember the definition of the density of matter, which is the relationship between mass and volume. The density can be calculated by means of the following formula.

[tex]Ro=m/V[/tex]

where:

Ro = density = 1 [gramm/cm³]

m = mass [gramm]

V = volume = 100 [cm³]

Now replacing:

[tex]m=Ro*V\\m=(1\frac{grm}{cm^{3} } )*100cm^{3} \\m=100[gram][/tex]

Answer:

100kPa

Explanation:

Given parameters:

Initial volume of gas  = 1L

Pressure  = 200kPa

Final volume  = 2L

Unknown:

Final pressure  =  

Solution:

According to Boyles's law "the volume of fixed mass of gas of a gas varies inversely as the pressure changes if temperature is constant".

  Mathematically;

            P₁V₁  = P₂V₂

P and V are volume and pressure

1 and 2 are initial and final states

  Insert the parameters and solve;

            200 x 1  = P₂ x 2

                 P₂  = 100kPa

Answer:

the keys will make it back to John.

Explanation:

In order to find out if the keys will reach John or not, we can use the formula of projectile motion to find the maximum height reached by the keys:

H = V²Sin²θ/2g

where,

V = Launch Speed = 18 m/s

θ = Launch Angle = 40°

g = 9.8 m/s²

Therefore,

H = (18 m/s)²[Sin 40°]²/(2)(9.8 m/s²)

H = 6.83 m

Hence, the maximum height that can be reached by the projectile or the keys is greater than the height of John's Balcony(5.33 m).

Therefore, the keys will make it back to John.

Yes, Key will surely reach back to John.

Given that;

Velocity v = 18 m/s

θ Angle = 40°

g = 9.8 m/s²

Computation:

By using maximum height formula

H = [v²][sin²θ]/2g

H = (18)²[Sin 40°]²/[(2)(9.8)]  

H = 6.83 m

6.83 meter is more then 5.33 meter,

So,

Key will surely reach back to John.
