<span>The answer in the space provided is drive error. It is because not only that hard braking or abrupt acceleration causes skids, but it is also caused by a driving error where in the individual is likely to cause the skid when he or she cause a driving error.</span>

Answer: travelling too fast, doing a very aggressive or sudden turn, or bad conditions of the road.

Explanation:

Skidding is the slip of the wheels over the road caused by loss of traction between the tires and the pavement.

When the tires slip, they lose their grip on the ground and tend to move according to the inertia or the imperfections of the surface instead of following the desired route. So, the driver is not in control of the vehicle any more.

The traction is how hard the wheels are attached to the ground, whenever you are forced to brake hard, accelerate abruptly, make a sudden turn or the surface of the road is covered with water, sand, or oil, the wheels will not adhere enough to the road and the car skids.

Also the conditions of the tires are important: when the tires lose their design, they will not have the capacity to displace the water and will slide easilyover wet surfaces.

Nine tree lights are connected inparallel across 120-V potential difference. The cord to the wall socket carries a current of 0.
jok3333 [9.3K]

Answer:

a)3000ohm

b)4.44mA

Explanation:

a) we were given a Nine tree lights connected inparallel across 120-V potential difference, since the resistor are in parallel we use the expresion below

1/R(total)= 1/R₁ + 1/R₂ + 1/R₃ + 1/R₃ +.... 1/R₉

But according to ohm'law which can be expressed below

V=IR

R=V/I

R(total)= 120/0.36

= 333.33ohm

1/R(total)= 1/R₁ + 1/R₂ + 1/R₃ + 1/R₃ +.... 1/R₉

R₁=R₂ =R₃ =R₄= R₅=R₆=R₇=R₈=R₉

1/R(total)=9/R

1/333.33= 9/R

R= 3000ohm

Therefore, the resistance is 3000ohm

b)the bulbs were connected in series here, then for series connection we use below expression

R₁=R₂ =R₃ =R₄= R₅=R₆=R₇=R₈=R₉

R(total)=9R

= 9*3000

=27000ohm

I=VR

I=V/R

I= 120/27000

= 4.44*10⁻³A

4.44mA

Therefore, the current is 4.4mA

An electric clothes dryer draws 15 a of current from a 240-v wall outlet. how much power, in watts, does it use?
Nataly [62]
The power consumed by the electric clothes dryer may be calculated by the following equation,

    P = I x V

where P is the power, I is the current in amperes, and V is the voltage in volts. Substituting the known values from the given above,

  P = (15 A)(240 V)
  P = 3600 watts

Therefore, the power consumed by the electric clothes dryer is equal to 3600 watts.

A force that causes an object to change its motion is called?
GarryVolchara [31]
Unbalanced force.

The definition of an unbalanced force is a force that changes the position, speed or direction of the object to which it is applied.

When an object is still it means that is is balanced force. So you would need to add more force to another side to make it move. Which is unbalanced force.
