They are energy inefficient
Explanation:
The main reason why we must change away from using incandescent lighting bulbs is because of their energy inefficiency.
- Much of the power consumed is used in producing heat in an incandescent bulb.
- Therefore, they are energy inefficient.
- Energy saving bulbs produces less heat and they are more durable.
- Most energy saving bulbs are typically more expensive.
- Most incandescent bulbs are also not environmentally friendly.

Answer: a=-2.4525 m/s^2
d=s=190.3 m
Explanation:The only force that is stopping the car and causing deceleration is the frictional force Fr
Fr = 25% of weight
W=mg
W=1750*9.81
W=17167.5
Hence

Frictional force is negative as it acts in opposite direction
According to newton second law of motion
F=ma
hence


given
u= 110 km/h
u=110*1000/3600
u=30.55 m/s
to get t we know that final velocity v=0

The statement that is true is a. the large bran muffin contains more heat energy. This statement holds true because of the equation E=mc2. E= Energy, m=mass and c=the speed of light. Although both muffins are at room temperature, the larger will theoretically have more heat energy because it has more mass.
<span>(1) Connect one red clamp to the positive (+) battery post of the "dead" battery.(2) Connect the other red clamp to the positive (+) post of the good battery.(3) Connect one black-end clamp to the negative (-) post of the good battery.(4) Carefully connect the other black-end clamp to some large metallic part of your car's engine block. Never connect it to the negative (-) post of the "dead" battery because this causes sparking which could ignite battery gases.<span>hope this helps </span></span>
