Answer:

\huge\boxed{\sf t = 2298.57\ secs}

Explanation:

<u>Given:</u>

Speed = v = 0.7 m/s

Distance = S = 1 mile = 1609 metre

<u>Required:</u>

Time = t = ?

<u>Formula :</u>

v = S/t

<u>Solution:</u>

v = S/t

t = S/v

t = 1609 / 0.7

t = 2298.57 secs

Answer:

\Huge \boxed{\mathrm{2298.57 \ seconds}}

\rule[225]{225}{2}

Explanation:

\displaystyle \sf Speed = \frac{Distance \ covered  }{Time \ taken}

\displaystyle \sf s = \frac{d  }{t}

The speed is 0.7 m/s.

The distance covered is 1609 m.

\displaystyle \sf 0.7 = \frac{1609  }{t}

Multiplying both sides by <em>t</em>.

Then dividing both sides by 0.7.

\displaystyle \sf t = \frac{1609  }{0.7}

\sf t= 2298.57

It would take 2298.57 seconds.

\rule[225]{225}{2}

7.5 x 10⁻¹¹m. An electromagnetic wave of frecuency 4.0 x 10¹⁸Hz has a wavelength of 7.5 x 10⁻¹¹m.

Wavelength is the distance traveled by a periodic disturbance that propagates through a medium in a certain time interval. The wavelength, also known as the space period, is the inverse of the frequency. The wavelength is usually represented by the Greek letter λ.

λ = v/f. Where v is the speed of propagation of the wave, and "f" is the frequency.

An electromagnetic wave has a frecuency of 4.0 x 10 ¹⁸Hz and the speed of light is 3.0 x 10⁸ m/s. So:

λ = (3.0 x 10⁸ m/s)/(4.0 x 10¹⁸ Hz)

λ = 7.5 x 10⁻¹¹m

Two hockey pucks with mass 0.1 kg slide across the ice and collide. Before the collision, puck 1 is going 13 m/s to the east and
ohaa [14]

Answer:

13 m/s east

Explanation:

We can solve the problem by using the law of conservation of momentum, which states that the total momentum before the collision is equal to the total momentum after the collision:

p_i = p_f \\m u_1 + m u_2 = m v_1 + m v_2

where

m = 0.1 kg is the mass of each puck

u1 = +13 m/s is the initial velocity of puck 1

u2 = -18 m/s is the initial velocity of puck 2 (here I assume the west direction to be the negative direction, so I put a negative sign)

v1 = -18 m/s is the final velocity of puck 1

v2 = ? is the final velocity of puck 2

Simplifying m from the formula and substituting the data, we can find the final velocity of puck 2, v2:

v_2 = u_1 + u_2 - v_1 = +13 m/s + (-18 m/s) - (-18 m/s) = +13 m/s

And the positive sign means that puck 2 is moving east.
