What is the acceleration experienced by a car that takes 10s to reach 27m/s from rest

Physics
1 answer:
Lerok [7]2 years ago
5 0

|acceleration|  =  (change in speed) / (time for the change)

Change in the car's speed = (27 - 0) = 27 m/s
Time for the change  =  10 sec

|acceleration| = (27 m/s) / (10 s)  =  2.7 m/s² .

That's the magnitude of the car's acceleration.
We don't know anything about its direction.

Two resistors, A and B, are connected in a series circuit with a battery. The resistance of A is twice that of B. Which resistor
IgorC [24]

Answer:

A dissipates more power.

Explanation:

  • In a series circuit, the current is the same at any point in it.
  • The power dissipated in any resistor follows Joule's law, as follows:

        P = I^{2} * R

  • So, for a given current, the power is directly proportional to the resistance of the resistor.
  • In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.

1. How much heat must be absorbed by 375 grams of water to raise its
antiseptic1488 [7]

Answer:

39225J

Explanation:

Given parameters:

Mass of water  = 375grams of water

Change in temperature  = 25°C

Specific heat capacity of water  = 4.184J/g°C

Unknown:

Amount of heat absorbed  = ?

Solution:

To solve this problem, we use the expression below:

      H  = m c Ф  

H is the heat absorbed

m is the mass

c is the specific heat capacity

Ф is the change in temperature

  Insert the parameters and solve;

      H  = 375 x 4.184 x (25) = 39225J

Which would most likely cause the cylinder head temperature and engine oil temperature gauges to exceed their normal operating r
dusya [7]

Answer: Using fuel that has a lower-than-specified fuel rating.

Explanation:

Most likely, what causes the cylinder head temperature and engine oil temperature gauges to exceed their normal operating ranges is using fuel that has a lower-than-specified fuel rating. This can lead to detonation of the engine which is the tendency for the fuel to pre-ignite or auto-ignite in an engine's combustion chamber.The cylinder head and the engine oil are part of the automobile systems that helps in fuel combustion.
