holiday lights are often connected in series and use special lamps that short out when the potential difference across a lamp in

Nuetrik [128]4 years ago
4 0

Explanation:

If there isn't the shorting mechanism, the whole set will be blown if anyhow one lamp burns out. Since having blown out several lamps and then shorted, the overall resistance of the remaining operating lamps will be decreased  resulting in an increased working current that is adequate to blast the fuse.

Use your data to predict what a 400g bag would weigh.
Kobotan [32]

3.92N

Explanation:

Given mass:

Mass of bag = 400g

The mass of a substance is the amount of matter it contains.

Weight of a substance is the vertical force acting on a body in the presence of gravity.

  Weight = mass x gravity

Since the mass of the bag is 400g;

 Now we convert to kg

   1000g  = 1kg

   400g = \frac{400}{1000}  =  0.4kg

  Weight of bag = 0.4kg x 9.8m/s²

   Weight of bag = 3.92N

A cricketer moves his hands backwards when holding a catch
lisov135 [29]
By doing this he increases the time due to which the rate of change momnetemdecreases. that means the ball comes to rest gently and does not hurt the fielder. but, if does not move his hand backwards, then the ball would come to rest in a fraction of second with a high rate of change of momentum. the ball will exert a lot of force on the hands of the fielder which will hurt him.

In a machine shop, a hydraulic lift is used to raise heavy equipment for repairs. The system has a small piston with a cross-sec
Mrac [35]

Answer:

F_s=1075.9493\ N

Explanation:

Given:

  • area of piston on the smaller side of hydraulic lift, a_s=0.075\ m^2
  • area of piston on the larger side of hydraulic lift, a_l=0.237\ m^2
  • Weight of the engine on the larger side, W_l=3400\ N

Now, using Pascal's law which state that the pressure change in at any point in a confined continuum of an incompressible fluid is transmitted throughout the fluid at its each point.

P_s=P_l

\frac{F_s}{a_s}=\frac{W_l}{a_l}

\frac{F_s}{0.075} =\frac{3400}{0.237}

F_s=1075.9493\ N is the required effort force.
