This 200-kg horse ran the track at a speed of 5 m/s. What was the average kinetic energy?

MrRissso [65]

Answer:

Explanation:

The average kinetic energy can be found by using the formula

$k = \frac{1}{2} m {v}^{2} \\$

m is the mass

v is the velocity

From the question we have

$k = \frac{1}{2} \times 200 \times {5}^{2} \\ = 100 \times 25$

We have the final answer is

Hope this helps you

2. A Formula One race car speeds up from rest to 27.8 m/s in a distance of 25 meters.

Nadya [2.5K]

Answer:

Correct answer: a = 15.46 m/s²

Explanation:

The formula for accelerated movement with the given data is:

V² - V₀² = 2 · a · d where the initial velocity V₀ and the final V

Since the initial velocity V₀ is zero, the formula is:

V² = 2 · a · d => a = V² / (2 · d) = 27.8² / (2 · 25) = 772.84 / 50 = 15.46 m/s²

a = 15.46 m/s²

The electric field between the plates of a parallel-plate capacitor is horizontal, uniform, and has a magnitude E. Asmall object

kirza4 [7]

Answer:

$m = 0.041 kg$

Explanation:

As we know that the small particle is in equilibrium at an angle of 16 degree with the vertical

so here we can use force balance in vertical and horizontal direction

$T cos\theta = mg$

$T sin\theta = qE$

now from above equation we have

$T = \sqrt{(mg)^2 + (qE)^2}$

also by division of above two equations we have

$\frac{qE}{mg} = tan\theta$

$qE = mg tan\theta$

now from above equation again

$T = \sqrt{(mg)^2 + (mg)^2 tan^2\theta}$

$T = mg sec\theta$

$0.420 = m(9.81) sec 16$

$m = 0.041 kg$

Genetically-Modified Organisms (GMOs) are currently being developed for agriculture. Currently commercialized GM crops in the U.

kirza4 [7]

D. There's not enough research surrounding it. A big question is if they have side effects due to genetic modification that we don't know of.

(Not sure if you had D eliminated or? But it should be the correct answer)
