Because when your running any experiment there will always be an experimental error so always be ready for it so that you can correct that error in your experiment
Answer:
Latent heat
Latent heat is the heat needed to change a state without a change in temperature.
Explanation:
Hope this helps :D
Force applied by the lever to the object=2700 N
Explanation:
Mechanical advantage= 
mechanical advantage= 5.4
effort force= 500 N
we need the load force
5.4= load/500
load=2700 N
Thus the force applied by the lever to the object=2700 N
Answer:
The correct option is thermogram
Explanation:
A thermogram is an image that is produced by thermographic cameras that are usually used to detect radiation (thermal energy released by a body) within a long-infrared range of electromagnetic spectrum. This process is a part of infrared imaging science which is useful in the diagnosis of breast cancer and some other forms of tumors.
We use the formula: p = E/c where E = hc / λ. hence, p = h/ λ. where h is the Planck's constant: 6.62607004 × 10-34 m2 kg / s and <span>λ is the wavelenght.

a) p = <span>6.62607004 × 10-34 m2 kg / s / 0.1 x10^-9 m = 6.62607 x 10-24 m kg/s
</span>b) p = 6.62607004 × 10-34 m2 kg / s / 3 x10^-2 m = 2.20869 <span>x 10-32 m kg/s
</span>b) p = 6.62607004 × 10-34 m2 kg / s / 2 x10^-9 m = 3.3130 <span>x 10-25 m kg/s</span>
