Answer:

Q = 3087460 J

Explanation:

As we know that first ice will convert into water

then water will heat to 100 degree celcius and then it will converted into vapor and then its temperature is raised to 110 degree C

First we will find the heat to take the ice at 0 degree and then convert it into water

Q_1 = ms_{ice}\Delta T + mL

Q_1 = 1(2100)(0 - (-20)) + 1(335000)

Q_1 = 42000 + 335000 = 377000 J

Now heat required to take it to 100 Degree then convert into vapor and then raise temperature to 110 degree

Q_2 = 1(4186)(100 - 0) + (1)(2250000) + 1(4186)(110 - 100)

Q_2 = 2710460 J

So total heat required is given as

Q = Q_1 + Q_2

Q = 377000 + 2710460

Q = 3087460 J

Explanation:

It takes time for sound waves to go through a large area. It takes longer if people are in the area rather than it is empty.

You build a grandfather clock, whose timing is based on a pendulum. You measure its period to be 2s on Earth. You then travel wi
Elenna [48]

Answer:

\frac{g_{2}}{g_{1}} = \frac{1}{4}

Explanation:

The period of the simple pendulum is:

T = 2\pi\cdot \sqrt{\frac{l}{g} }

Where:

l - Cord length, in m.

g - Gravity constant, in \frac{m}{s^{2}}.

Given that the same pendulum is test on each planet, the following relation is formed:

T_{1}^{2}\cdot g_{1} = T_{2}^{2}\cdot g_{2}

The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:

\frac{g_{2}}{g_{1}} = \left(\frac{T_{1}}{T_{2}} \right)^{2}

\frac{g_{2}}{g_{1}} = \left(\frac{2\,s}{4\,s} \right)^{2}

\frac{g_{2}}{g_{1}} = \frac{1}{4}

Which accident will be more damaging, collision between two trucks
Vitek1552 [10]

Answer:

collision between truck

Explanation:

Answer. Collision between trucks, because more is the mass, more is the inertia and therefore more is the momentum. Mass of the trucks is more than that of cars so collision of trucks will cause more damage.
