That depends on the values of the resistors.
If the same two resistors are used in both cases, then the total resistance is more in series and less in parallel.
Here's a catchy little factoid for ya:
-- In series, the total resistance is more than the biggest single one.
-- In parallel, the total resistance is less than the smallest single one.

A bird is standing on an electric transmission line carrying a large amount of current. Find the power dissipated by the bird If the
current it experiences is 1.35^-10 A which results in a potential difference of .0054V.
Side Note:
(I know the answer is 7.3 x 10^-11 W, I just don’t know how to get it)
P = 7.3 × 10^-13 Watt
Explanation:
First of all, are you sure that what you have is the right answer?
Anyway, the definition of power dissipated is given by
P = I^2×R
where I is the current and R is the resistance. But we also know from Ohm's law that
V = IR
so we can rewrite the equation for power P as
P = I^2R = I(IR) = VI
= (0.0054 volt)(1.35 × 10^-10 A)
= 7.3 × 10^-13 Watt
A car accelerates at a rate of 13m/s^2[S]. If the car's initial velocity is 120km/h[N]. What will its final velocity be in m/s, after two seconds.
Answer:
the final velocity of the car is 59.33 m/s [N]
Explanation:
Given;
acceleration of the car, a = 13 m/s²
initial velocity of the car, u = 120 km/h = 33.33 m/s
duration of the car motion, t = 2 s
The final velocity of the car in the same direction is calculated as follows;
v = u + at
where;
v is the final velocity of the car
v = 33.33 + (13 x 2)
v = 59.33 m/s [N]
Therefore, the final velocity of the car is 59.33 m/s [N]

For every 120 joules of energy input a car wastes 85 joules , find the useful energy output of the car ?
Answer:
35 Joules
Explanation:
Applying
Input Energy(Q) = Useful energy output(U)+Wasted Energy(W)
Q = U+W.............................. Equation 1
Make U the subject of the equation
U = Q-W................... Equation 2
From the question,
Given: Q = 120 Joules, W = 85 Joules
Substitute these values into equation 2
U = 120-85
U = 35 Joules
A projectile is launched from the ground with an initial velocity of 12ms at an angle of 30° above the horizontal. The projectile lands on a hill 7.5m away. The height at which the projectile lands is most nearly
A- 1.78m
B- 3.10m
C- 5.34m
D- 6.68m
E- 12.0m
Answer:
A. 1.78 m
Explanation:
Given;
initial velocity of the, u = 12 m/s
angle of projection, θ = 30°
the range of the projectile, R = 7.5 m
To obtain the height through which the projectile lands, we must calculate the maximum height reached by the projectile.
[tex]H = \frac{u^2\ sin^2\theta}{2g} \\\\H = \frac{(12)^2\times (sin(30))^2}{2 \times 9.8} \\\\H = \frac{144 \times (0.5)^2}{19.6} \\\\H = 1.84 \ m[/tex]
Therefore, the height is most nearly 1.78 m

A traveler at Newark airport pulls his 294N suitcase with constant velocity to the check-in counter applying a force of 159N at an angle of 37 degrees with the horizontal. Calculate the Normal force, frictional force and the coefficient of friction between the suitcase and the airport floor.
Answer:
N = 198.3 N, fr = 126.98 N and μ = 0.64
Explanation:
For this exercise we must use the translational equilibrium condition.
Let's set a reference system with the x-axis horizontally and the y-axis vertical. Let's use trigonometry to decompose the applied force
cos θ = Fₓ / F
sin θ = F_y / F
Fₓ = F cos θ
F_y = F sin θ
Fₓ = 159 cos 37 = 126.98 N
F_y = 159 sin 37 = 95.69 N
Y axis
N + F_y - W = 0
N = W - F_y
N = 294 - 95.69
N = 198.3 N
X axis
Fₓ -fr = 0
Fₓ = fr
fr = 126.98 N
the expression for the friction force is
fr = μ N
μ = fr / N
μ = 126.98 / 198.3
μ = 0.64

A student uses 80 joules of energy to lift a backpack in a time of 0.75 seconds. How much power
does the student have?
Answer:
P = 106.7 W
Explanation:
Given that,
Work done in lifting a backpack, W = 80 J
It is lifted in 0.75 seconds
We need to find the power of the student. The power of an object is defined as work done per unit time. So,
[tex]P=\dfrac{W}{t}[/tex]
Put all the values,
[tex]P=\dfrac{80}{0.75}\\\\P=106.7\ W[/tex]
So, the power of the student is 106.7 W.
Using the diagram above, the coefficient of kinetic friction for copper is ____ (Your answer should be given to the nearest thousandths.)
This coefficient _____ applies to all similar copper surfaces.
Answer:
μ= 0.0375, kinetic
Explanation:
For this exercise we set a reference system with the x axis parallel to the chord
Y axis
N - W = 0
N = W
X axis
T - fr = 0
the expression for the friction force is
fr = μ N
we substitute
T - μ W = 0
μ = T / W
we calculate
μ = 1.5 / 40
μ= 0.0375
coefficient of kinetic friction
Tyra made the following bar graph shown to represent the relative distances of four different astronomical bodies from Earth.
The title of the bar graph is Distance of Bodies in Space from Earth. Four bars are labeled A, B, C, and D. Bar C is the shortest. Bar D is about three times the size of bar C. Bar A is about six times the size of bar C. Bar B is about eight times the size of bar C.
If D represents Mercury, which of the following could be represented by B and C?
B could be the moon, and C could be Venus.
B could be Venus, and C could be the moon.
B could be the moon, and C could be Jupiter.
B could be Jupiter, and C could be the moon.
Answer: D
Choice A calls B the moon which is incredibly tiny compared to Venus so this is wrong, choice B calls B Venus which is a relatively small planet and C the moon... that is a bit overkill so no. Choice C says B is the moon and C is Jupiter, Jupiter being the largest planet this is a easy no, leaving D to be the only logical and correct answer.
Explanation: MARK ME BRAINLIEST PLZZZZZZZZZZzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

What is the product of an oxidation reaction?
Ozone
Oxygen
Oxide
Answer:
Oxide
Explanation:
Ozone and oxygen are oxidising agents
[tex]O _{3} \: \: ozone \\ \\ O _{2} \: \: oxygen[/tex]
Answer:
Oxygen
Explanation:
The name oxidation actually originates from the word oxygen so the question answers it's self.
In case you don't know what oxidation is:
Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species increases. Oxidation doesn't necessarily involve oxygen! Originally, the term was used when oxygen caused electron loss in a reaction.

The figure below shows two people ice-skating. Person A collides with
person B. After the collision they move together with the same velocity.
Calculate the mass, m, of person B.
Before collision
After collision
Person A
mass = 60 kg
Person B
mass, m
Person A and person B
moving off together
Speed of
Person A -
5.5 m/s
Speed of
Person B -
2.0 m/s
Speed of Person A and
Person B = 4.0 m/s
mB = 45 kg
Explanation:
Using conservation of linear momentum,
mAvA + mbvB = (mA + mB)v
(60 kg)(5.5 m/s) + (2.0 m/s)mB = (60 kg + mB)(4.0 m/s)
(330) + 2mB = 240 + 4mB
2mB = 90
mB = 45 kg
