I believe your answer is d. Derek is hungry or needs to have his diaper changed.
Option c could be correct but option d seems more likely
I hope this is the answer you're looking for and good luck.
Real-world efficiencies are generally very high, in the 90 percent range. FALSE.
<span>Warming up before exercising
prevents the cause of injuries, reducing muscle strain and improve muscle
performance. The answer is letter D. The goal of warming up is to increase body
temperature, increase neural activation, warm up the joints for our body to not
be shocked during exercising. It will get your blood flowing, clears waste from
your muscles, and brings fluids to your joints. It will improve the performance
in exercising by actively moving the joints and increase in muscular
performance at the same time eliminating injuries along the way. </span>
Answer:
50 cm
Explanation:
Given that
Focal length of the mirror, f = 25 cm
Distance of the image, u = ?
Distance of the object, v = 50 cm
The formula for the focal length of a convex mirror is given by the relation
1/f = 1/u + 1/v,
where each of the parameters are exactly the same as what I've defined above. So now, if we plug in the values, we have
1/25 = 1/u + 1/50
1/u = 1/25 - 1/50
1/u = (2 - 1)/50
1/u = 1/50
u = 50 cm
So then, we can conclude that the size of the image is 50 cm
True. hope this is right:)
