3 0

Answer:

c. Joints allow the roadway to expand and contract as cars put force on the bridge

Explanation:

The reasons why joints are allowed on roadway is to accommodate the contraction and expansion of the road as cars put force on them.

  • Most materials used in making roadways are susceptible to expansion and contraction.
  • When a measure of force is applied their length either increases or decreases depending on the type of force.
  • To accommodate these changes, joints are placed in roadways

Using a 1-kW heater for one hour consumes more energy than using a 100-W bulb for twenty-four hours. Please select the best answ
Ierofanga [76]
Power is the amount of work done per unit of time. It will have units of Watts which is equal to Joules per second. We determine the energy of each system above by multiplying the power with time. We do as follows:

E(heater) =1000 W (1 hr) (3600s/hr) = 3,600,000 J
E(bulb) = 100 W (24 hr) (3600s/hr) =   8,640,000 J

Therefore, the answer would be false. It is the bulb that consumes more energy.
