Answer:

halved.

Explanation:

Given the following data;

Potential difference = constant

Resistance = 2 * resistance = 2R

To find the current I;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Making current (I) the subject of formula, we have;

[tex] I = \frac {V}{R} [/tex]

Substituting into the formula, we have;

[tex] I = \frac {V}{2R} [/tex]

[tex] I = \frac {1}{2} * \frac {V}{R} [/tex]

[tex] I = \frac {1}{2} * I [/tex]

Therefore, if the resistance of the resistor is doubled, the current through the resistor is halved.

Answer:

Explanation:

I got everything but i. Don't know why but it's eluding me. So let's do everything but that.

a. PE = mgh so

   PE = (2.5)(98)(14) and

   PE = 340 J

b. [tex]KE=\frac{1}{2}mv^2[/tex] so

   [tex]KE=\frac{1}{2}(2.5)(14)^2[/tex] and

   KE = 250 J

c. TE = KE + PE so

   TE = 340 + 250 and

   TE = 590 J

d. PE at 8.7 m:

   PE = (2.5)(9.8)(8.7) and

   PE = 210 J

e. The KE at the same height:

   TE = KE + PE and

   590 = KE + 210 so

   KE = 380 J

f. The velocity at that height:

   [tex]380=\frac{1}{2}(2.5)v^2[/tex] and

   [tex]v=\sqrt{\frac{2(380)}{2.5} }[/tex] so

   v = 17 m/s

g. The velocity at a height of 11.6 m (these get a bit more involed as we move forward!). First we need to find the PE at that height and then use it in the TE equation to solve for KE, then use the value for KE in the KE equation to solve for velocity:

   590 = KE + PE and

   PE = (2.5)(9.8)(11.6) so

   PE = 280 then

   590 = KE + 280 so

   KE = 310 then

   [tex]310=\frac{1}{2}(2.5)v^2[/tex] and

   [tex]v=\sqrt{\frac{2(310)}{2.5} }[/tex] so

   v = 16 m/s

h. This one is a one-dimensional problem not using the TE. This one uses parabolic motion equations. We know that the initial velocity of this object was 0 since it started from the launcher. That allows us to find the time at which the object was at a velocity of 26 m/s. Let's do that first:

   [tex]v=v_0+at[/tex] and

   26 = 0 + 9.8t and

   26 = 9.8t so the time at 26 m/s is

   t = 2.7 seconds. Now we use that in the equation for displacement:

   Δx = [tex]v_0t+\frac{1}{2}at^2[/tex] and filling in the time the object was at 26 m/s:

   Δx = 0t + [tex]\frac{1}{2}(-9.8)2.7)^2[/tex] so

   Δx = 36 m

i. ??? In order to find the velocity at which the object hits the ground we would need to know the initial height so we could find the time it takes to hit the ground, and then from there, sub all that in to find final velocity. In my estimations, we have 2 unknowns and I can't seem to see my way around that connundrum.

Answer:

change in momentum

Explanation:

using newton's second law,

F = m ( v - u ) / t....

Ft = mv - mu

impulse is either Ft ( product of force applied and the time taken for its action )

or impulse is mv - mu ( change in momentum )

Answer:

The factors affecting climate are latitude, altitude, land and water distribution, distance from the sea, distance from the sun, prevailing winds and ocean currents, surface covering the land, volcanism, solar constant sunspots, wind direction and nature of mountain chains, mountain barriers.

There are six major climatic controls. They are:

Latitude: As the earth is round, sunlight does not reach everywhere equally. The temperature decreases as we move from the equator to the poles.

Altitude: As we move from the surface of the earth to the higher altitudes, the temperature decreases.

Pressure and wind system: The pressure and wind system of any area depend on the latitude and altitude of that place. Thus, it influences the temperature accordingly.

Distance from the sea: Coastal regions are cooler as compared to interior regions. As the distance from the sea increases, its influence decreases and the people experience extreme weather conditions.

Ocean currents: Cold ocean currents flowing over a region will decrease the temperature of that area whereas warm currents will increase the temperature.

Relief features: Relief features are the barriers that block currents from entering the country. High mountains act as barriers for cold or hot winds.

First of all, what a weight is? weight is m × g.. and when a person is in space then the force of gravity isn't acting on him or her, so yeah it will not have weight, but remember gravity is a very very low, now if a body has more mass, more gravity will act on it right? just imagine the mass of a person and that of earth.. now yes, earth will do exert a force on the astronaut but is negiligable.

Answer:

327.6 is the answer but there is 2 sig figs in 14 so change it to 330

so 330 is the final answer

hope this helps

have a good day :)

Explanation:

The multiplication product of 23.4 × 14  is 327.6. However, there is only two significant figures in 14. So we have to take the answer in 2 significant figure. Hence, the product can be written as 3.3 × 10².

Significant figures are number of digits which  can be counted as certain values associated with some uncertainties as well. There are certain rules regrading the count of significant figures in a number.

The zeros after a non-decimal number cannot be taken as significant. For eg, in 4500, there are only two significant figures. The common rule for all the arithmetic operation is that, the significant figures in the product have to be equal to the number of significant figure in the number in the operation with least significant figures.

Here, the one with least significant figures is 14. It have two significant figures. Now, product of the two numbers is :

23.4 × 14 = 327.6

But the rounded product for correct significant figure is 3.3 × 10².

Answer:

Explanation:

f divided by m = a

Answer:

La tensión es 85.3 N.

Explanation:

Cuando el objeto gira en dirección horizontal, la sumatoria de fuerzas se puede calcular usando la segunda ley de Newton:  

[tex] \Sigma F_{x} =ma_{c} [/tex]

[tex] T = ma_{c} [/tex]  

Dado que el movimiento es horizontal, el peso (que está en el eje y) no contribuye en la sumatoria de fuerzas en el eje x. Por lo que la única fuerza actuando sobre el objeto en la dirección del movimiento es la tensión.  

En donde:                                          

m: es la masa del objeto = 200 g = 0.200 kg

[tex]a_{c}[/tex]: es la aceleración centrípeta

La aceleración centrípeta viene dada por:  

[tex]a_{c} = \omega^{2} r[/tex]

En donde:    

ω: es la velocidad angular del objeto = 3 rev/s

r: es el radio = 1.20 m

Entonces, la tensión es:

[tex]T = m\omega^{2} r = 0.200 kg(3\frac{rev}{s}*\frac{2\pi rad}{1 rev})^{2}*1.20 m = 85.3 N[/tex]

Por lo tanto, la tensión es 85.3 N.

Answer and Explanation:

They are both correct.

This is because potential energy is when there is potential for the object to have energy, while kinetic energy is energy that is moving already.

So, as the ball falls, it loses its potential energy, or "still/Stalled" energy, and gains kinetic energy, or moving energy.

As a sample of water turns to ice, A new molecules are formed.

Answer:

i not sure

Explanation:

There are approximately 6.24 x 10¹⁸ electrons contained in 1.0 C of charge. The mass of the electron in 1.0 C of charge remains the same as the mass of an electron, which is approximately 9.109 x 10⁻³¹ kg.

We may utilise the elementary charge, which represents the charge of a single electron, to calculate how many electrons are present in 1.0 C of charge. It is estimated that the elementary charge is 1.602 x 10-19 C.

Number of electrons = Charge ÷ Elementary charge

Number of electrons = 1.0 C ÷ (1.602 x 10⁻¹⁹ C)

Calculating the division:

Number of electrons ≈ 6.24 x 10¹⁸ electrons

Therefore, there are approximately 6.24 x 10¹⁸ electrons contained in 1.0 C of charge.

It is crucial to remember that the electron's mass is unaffected by the charge when considering the electron's mass in 1.0 C of charge. Regardless of the charge it carries, an electron has a mass of about 9.109 x 10⁻³¹ kg.

Thus, the mass of one electron, which is roughly 9.109 x 10⁻³¹ kg, remains constant in 1.0 C of charge.
