Resistance in a series circuit will​

Physics
1 answer:
ra1l [238]4 years ago
6 0

Answer:

Answer:The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.

A jetliner rolls down the runway with constant acceleration from rest, it reaches its take off speed of 250 km/h in 1 min. What
nlexa [21]

Answer:

Acceleration, a=14970.05\ km/h^2

Explanation:

Given that,

Initially, the jetliner is at rest, u = 0

Final speed of the jetliner, v = 250 km/h

Time taken, t = 1 min = 0.0167 h

We need to find the acceleration of the jetliner. The mathematical expression for the acceleration is given by :

a=\dfrac{v-u}{t}

a=\dfrac{250}{0.0167}

a=14970.05\ km/h^2

So, the acceleration of the jetliner is 14970.05\ km/h^2. Hence, this is the required solution.

A loop of wire is placed in a uniform magnetic field. Let ø be the angle between the direction of b and the normal. At which val
zaharov [31]

Answer:

B. 0 degrees

Explanation:

The magnetic flux through a certain area enclosed by a loop of wire immersed in a region with magnetic field is given by:

\Phi = B A cos \theta

where

B is the strength of the magnetic field

A is the area enclosed by the coil

\theta is the angle between the direction of the magnetic field and the direction of the normal to the coil

From the equation above, we see that the magnetic flux is maximum when

cos \theta=1

So when the field is parallel to the normal to the coil (so, when it is perpendicular to the coil), therefore when:

\theta=0^{\circ}

So, the correct option is

B. 0 degrees

A 120 V electric heater draws a current of 14.1 A. What is the resistance, in ohms?
Sav [38]

Answer:

8.5 ohms

Explanation:

from ohms law

V=IR

120=14.1R

divide both sides by 14.1

120/14.1=14.1R/14.1

R=8.5ohms

What would u expect the tides to be like during a first quarter moon?
kicyunya [14]

Answer:

During the first quarter or last quarter phase of the moon, when the sun and moon are perpendicular (at right angles) to each other in relation to the Earth, the tidal gravitational pulls interfere with each other, producing weaker tides, known as neap tides.
