Answer:

Fusion

Explanation:

The combination of two lighter nuclie and forms a new heavier nucleus and release and lot of amount of energy is called nuclear fusion.

To start the nuclear fusion reaction we need a very high temperature.

We get energy from sun, it is due to the nuclear fusion of hydrogen and forms helium.

You pull straight up on the string of a yo-yo with a force 0.24 N, and while your hand is moving up a distance 0.17 m, the yo-yo

Alex

Answer:

The transnational kinetic energy of the yo-yo is 0.083 J.

Explanation:

Given that,

Force=0.24 N

Distance in up= 0.17 m

Distance in down = 0.26 m

Mass of yo-yo = 0.057 kg

Initial speed = 2.4 m/s

Suppose we find the increase in the transnational kinetic energy of the yo-yo

The transnational kinetic energy is equal to the change in potential energy.

We need to calculate the transnational kinetic energy of the yo-yo

Using conservation of energy

$\Delta K.E=(mg-F)h$

Where, F = force

h = height

m = mass of yo-yo

Put the value into the formula

$\Delta K.E=(0.057\times9.8-0.24)\times0.26$

$\Delta K.E=0.083\ J$

Hence, The transnational kinetic energy of the yo-yo is 0.083 J.

You are on the roof of the physics building, 46.0 above the ground . Your physics professor, who is 1.80 tall, is walking alongs

Fudgin [204]

Answer:

3.6m

Explanation:

if you are at a building that is 46m above the ground, and the professor is 1.80m, the egg must fall:

46m - 1.80m = 44.2m

the egg must fall for 44.2m to land on the head of the professor.

Now, how many time this takes?

we have to use the following free fall equation:

$h=v_{0}t+\frac{1}{2}gt^2$

where $h$ is the height, $v_{0}$ is the initial velocity, in this case $v_{0}=0$ . $g$ is the acceleration of gravity: $g=9.81m/s$ and $t$ is time, thus:

$h=\frac{1}{2}gt^2$

clearing for time:

$2h=gt^2\\\frac{2h}{g}=t^2\\\sqrt{\frac{2h}{g}} =t$

we know that the egg has to fall for 44.2m, so $h=44.2$ , and $g=9.81m/s$ , so we the time is:

$t=\sqrt{\frac{2(44.2m)}{9.8m/s^2} }=\sqrt{\frac{88.4m}{9.81m/s^2} } =\sqrt{9.011s^2}= 3.002s$

Finally, if the professor has a speed of $v=1.2m/s$ , it has to be at a distance:

$d=vt$

and t=3.002s:

$d=(1.2m/s)(3.002s)=3.6m$

so the answer is the professor has to be 3.6m far from the building when you release the egg

An electrical heater is used to supply 245.0 J of energy to a 15.0 g sample of aluminum, originally at 310.0 K. Determine the fi

Softa [21]

Answer:

$T_f=328.1 K$

Explanation:

To determine the final temperature of the sample, we use the specific heat formular as follows:

$Q=mCp(T_f-T_0)\\T_f=\frac{Q}{mCp} +T_{0}\\mol Al= \frac{15g}{26.98gmol^{-1}}=0.555 mol\\T_f=\frac{245.0J}{0.555mol\times24.35Jmol^{-1}K^{-1}} +310.0K\\T_f=328.1 K$
