A 2 kg car accelerated from 10 m's to 20 m/s using a force of 3000N. How quickly did it
elena-14-01-66 [18.8K]

Answer:

the car accelerates in

\frac{1}{150}  \: or \: 0.006 \: second

Explanation:

here's the solution : -

we know,

=》

force = mass   \times acceleration

=》

acceleration =  \frac{force}{mass}

=》

a  =  \frac{3000}{2}

=》

a = 1500

so, acceleration = 1500 m/s^2

now,

=》

a =  \frac{v - u}{t}

here, a = acceleration, v = final velocity,

u = initial velocity, t = time taken.

So,

=》

1500 =  \frac{20 - 10}{t}

=》

1500 =  \frac{10}{t}

=》

t =  \frac{10}{1500}

=》

t = 0.006 \: sec

Please explain how to solve 17 and 18
andriy [413]

Answer:

17. h = l − l cos θ

18. 1.40 m

Explanation:

Let's call d the height of the triangle.  We can then say:

h = l − d

Using trig, we can write d in terms of l and θ:

d = l cos θ

h = l − l cos θ

If l = 6 m and l cos θ = 40°:

h = 6 − 6 cos 40

h ≈ 1.40

A monochromatic beam of light has a frequency
tatiyna

Answer:

5.24*10^{-19}J

Explanation:

The energy of a photon of light can be calculated from the following equation;

E=hf.....................(1)

where his Planck's constant and is given by,

h=6.63*10^{-34}Js

f is the frequency of the light and is given by 7.69*19^{14}Hz

So therefore,

E=6.63*10^{-34}*7.69*10^{14}\\E=5,24*10^{-19}J
