Answer:

See attachment

Explanation:

Electric devices can be connected into two types of configuration:

- Series: two devices are connected in series if they are along the same branch. In this case, the current flowing through the two devices is the same (but the potential difference across them is different)

- Parallel: two devices are connected in parallel if they are along two different branches that are connected to the same ends. In this case, the current flowing through the two devices is different, while the potential difference across them is the same.

The figure attached shows a circuit in which:

- The first 2 light bulbs on top are connected in parallel

- Then these 2 bulbs are connected in series to the light bulb on bottom

Interactive LearningWare 4.1 reviews the approach taken in problems such as this one. A 1800-kg car is traveling with a speed of
Lubov Fominskaja [6]

Answer:

F= 4788 N

Explanation:

Because the car moves with uniformly accelerated movement we apply the following formula:

vf²=v₀²+2*a*d Formula (1)

Where:  

d:displacement in meters (m)  

v₀: initial speed in m/s    

vf: final speed in m/s  

a: acceleration in m/s²

Data

d=36.9 m

v₀=14.0 m/s m/s    

vf= 0  

Calculating of the acceleration of the car

We replace dta in the formula (1)

vf²=v₀²+2*a*d

(0)²=(14)²+2*a*(36.9)

-(14)²= (73.8) *a

a= - (196) /  (73.8)

a= - 2.66 m/s²

Newton's second law of the car in direction  horizontal (x):

∑Fx = m*ax Formula (2)

∑F : algebraic sum of the forces in direction x-axis (N)

m : mass (kg)

a : acceleration  (m/s²)

Data

m=1800 Fkg

a= - 2.66 m/s²

Magnitude of the horizontal net force (F) that is required to bring the car to a halt in a distance of 36.9 m :

We replace data in the formula (2)

-F= (1800 kg) * ( -2.66 m/s² )

F= 4788 N

When is your weight is equal to mg?<br>​
Vinil7 [7]

Answer:

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg.

Calculate the magnitude of the total angular momentum of the woman–disk system. (assume that you can treat the woman as a point.
Mrac [35]
 <span>I of disk = 1/2MR² = (0.5)(230)(4.0)² = 1840 kgm² 
I of disk-woman system = I = 1/2MR² + md² = (50)(4.0)² = 1840 + 800 = 2640 kgm² 
L = Iw = (2640)(0.80)(2π) = 13,270 ≈ = 13,000 kgm²/s ANS
