Two resistors, A and B, are connected in series to a 6.0 V battery. A voltmeter connected across resistor A measures a potential difference of 4.0 V. When the two resistors are connected in parallel across the 6.0 V battery, the current in B is found to be 2.0 A. Find the resistances of A and B.

The standard form of the given exponential function is 120000.

By putting the number as a base and the number of repetitions as a little number to its upper right, a representation of repeated multiplications of the same number is known as an exponential form.

It is simpler to write repeated multiplication using base and exponents in the exponential form.

The equation f(x) = aˣ, in which the input variable x appears as an exponent and a as the base, describes an exponential function.

So, the given exponential function is,

1.2 x 10⁵

Here, 10 is the base and 5 is the exponent.

10⁵ = 100000

Therefore, the standard form of the given equation is,

1.2 x 100000 = 120000

Answer:

Explanation:

The standard equations of the parabolas are listed below:

In this question we have four case of parabolas with vertical axes of reference, whose standard formula is:

[tex]y - k = \frac{1}{4\cdot p}\cdot (x-h)^{2}[/tex]     (1)

Where:

Please notice that p < 0 when the directrix is above the focus, otherwise p < 0. The vertex is the midpoint of line segment between the directrix and the focus.

Now we proceed to derive the standard equations of the parabola:

1) Vertex:

(h, k) = 0.5 · (- 6, 4) + 0.5 · (- 6, - 3)

(h, k) = (- 6, 0.5)

Least distance:

p = - 3.5

y + 6 = - (1/14) · (x + 6)²

2) Vertex:

(h, k) = 0.5 · (0, - 4) + 0.5 · (0, - 5)

(h, k) = (0, - 4.5)

Least distance:

p = 0.5

y = (1/2) · (x + 4.5)²

3) Vertex:

(h, k) = 0.5 · (2, 3) + 0.5 · (2, 7)

(h, k) = (2, 5)

Least distance:

p = 2

y - 5 = - (1/8) · (x - 2)²

4) Vertex:

(h, k) = 0.5 · (- 2, - 6) + 0.5 · (- 2, - 4)

(h, k) = (- 2, - 5)

Least distance:

p = 1

y + 5 = (1/4) · (x + 2)²

Answer:

Why sex cells only need half the number of chromosomes compared to other cells in the body?  As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

Answer:

During Mitosis, the chromosomes split at G2 Phase.

Answer:

Potential energy does not have an absolute measurement. It is always relative to some reference point. Gravitational potential always increases when you go up and decreases when you go down. But the choice of a zero point is arbitrary.

If you’re dropping objects onto the ground, then choosing the ground as a zero point makes the calculations easier. But you could just as easily make the zero point the top of Mt. Everest, and all the answers would turn out the same. Up still means more energy and down means less, but now the PE of an object at sea level would have a negative sign, but not as negative as an object ten meters above sea level.

So everything would still work fine.

In fact, planetary astronomers take this idea to extremes. Instead of the top of Mt. Everest, they set the zero point for potential energy as infinitely high—so far “up” that gravity is so weak that going “up” another kilometer doesn’t gain you any energy. Then the value for potential energy everywhere else in the universe anywhere near a planet has a negative sign, but just as before, all the answers in relative terms turn out fine.

Explanation:

Volume expansivity = change in volume/original volume×temp change

Volume expansivity p = 3x

p = ∆V/V∆t

x is the linear expansivity

Given

x = 6 x 10^-4

p = 3x

p = 3(6 x 10^-5)

p = 18×10^-5

Volume = 100m³

∆t = 45-10 = 35°C

Required

Change in volume ∆V

Substitute the given values into the formula

18×10^-5 = ∆V/100(35)

18×10^-5 =∆V/3500

∆V = 3500×0.00018

∆V = 0.63m

Hence the increase in volume of the Mercury is 0.63n

Answer:

Maximum Height

Explanation:

The maximum height is the highest point reached by a projected body. At this point, final velocity, v of the body is equal to 0; because upward motion is at its peak and the body start to fall again.

Hence, final velocity v is always 0 at this maximum point and the direction of motion changes from upward to downward.

Final velocity at this maximum height is zero because of the directional change experied by the object and the fact that upward motion of the body terminates at this point.

Answer:

The final equilibrium temperature of the tin-water mixture is approximately 18.468 °C

Explanation:

The parameters of heat energy transfer from the tin to the water are given as follows;

The mass of the sample of tin, m₁ = 0.225 kg

The initial temperature of the tin, T₁ = 97.5 °C

The mass of the water into which the tin is dropped, m₂ = 0.115 kg

The initial temperature of the water, T₂ = 10.0 °C

The specific heat capacity of tin, c₁ = 230 J/(kg·°C)

The specific heat capacity of water, c₂ = 4,200 J/(kg·°C)

Let 'T' represent the final equilibrium temperature of the tin-water mixture, we have;

The heat lost by the tin, ΔQ[tex]_{tin}[/tex] = The heat gained by the water ΔQ[tex]_{water}[/tex]

∴  ΔQ[tex]_{tin}[/tex] = ΔQ[tex]_{water}[/tex]

Where;

ΔQ[tex]_{tin}[/tex] = m₁·c₁·(T₁ - T)

ΔQ[tex]_{water}[/tex] = m₂·c₂·(T - T₂)

By substitution, we have;

ΔQ[tex]_{tin}[/tex] = 0.225 kg × 230 J/(kg·°C) × (97.5°C - T)

ΔQ[tex]_{water}[/tex] = 0.115 kg × 4,200 J/(kg·°C) × (T - 10.0°C)

From ΔQ[tex]_{tin}[/tex] = ΔQ[tex]_{water}[/tex], we have;

0.225 kg × 230 J/(kg·°C) × (97.5°C - T) = 0.115 kg × 4,200 J/(kg·°C) × (T - 10.0°C)

∴ 5,045.625 J - 51.75 J/°C × T = 483 J/°C × T - 4,830 J

5,045.625 J + 4,830 J = 534.75 J/°C × T

∴ 534.75 J/°C × T = 9,875.625 J

T =  9,875.625 J/(534.75 J/°C) = 18.4677419 °C ≈ 18.468 °C

The final equilibrium temperature of the tin-water mixture, T ≈ 18.468 °C.

Answer:

306 m/s

Explanation:

Law of conservation of momentum

m1v1 + m2v2 = (m1+m2)vf

m1 is the bullet's mass so it is 0.1 kg

v1 is what we're trying to solve

m2 is the target's mass so it is 5.0 kg

v2 is the targets velocity, and since it was stationary, its velocity is zero

vf is the velocity after the target is struck by the bullet, so it is 6.0 m/s

plugging in, we get

(0.1 kg)(v1) + (5.0 kg)(0 m/s) = (0.1 kg + 5.0 kg)(6.0 m/s)

(0.1)(v1) + 0 = 30.6

(0.1)(v1) = 30.6

v1 = 306 m/s

The initial velocity of the bullet can be determined from the total momentum of the system. The velocity of the bullet was 306 m/s.

Momentum of a body is the product of its mass and velocity. For a collision, the momentum before and after collision will be the same for the colliding system.

Let m1 and m2 be the masses and u be the initial velocity and v is the final velocity.

then,  m1 u1  + m2 u2 = m1 v1  + m2 v2.

Given m1 = 5 kg

m2 =  0.1 kg

The velocity of the combined mass v = 6 m/s.

The momentum of the target is zero since it was stationary.

(0.1 × u1) = (0.1 + 5)6 m/s

(0.1 × u1) = 30.6 m/s

then u1 = 30.6/0.1 = 306 m/s

Therefore, the velocity of the bullet before hitting was 306 m/s.

Answer:

Explanation:

Answer:

Object's final momentum = 16.7 kg-m/s

Explanation:

Given that,

Impulse, J = 12.2 kg-m/s

Initial momentum, [tex]P_i=4.5\ kg-m/s[/tex]

We need to find the object's final momentum. We know that the impulse is equal to the change in momentum. So,

Impulse = change in momentum

[tex]J=P_f-P_i\\\\P_f=J+P_i\\\\P_f=12.2+4.5\\\\P_f=16.7\ kg-m/s[/tex]

So, the object's final momentum is 16.7 kg-m/s.

Given:

We know the relation,

→ [tex]Impulse = Change \ in \ momentum[/tex]

or,

→ [tex]J = P_f-P_i[/tex]

then,

→ [tex]P_f = J+P_i[/tex]

By substituting the values,

        [tex]= 12.2+4.5[/tex]

        [tex]= 16.7 \ kg-m/s[/tex]

Thus the above answer is right.
