Answer:
Shown by explanation;
Explanation:
The heat of the sample = mass ×specific heat capacity of the sample × temperature change(∆T)
Assumption;I assume the mass of the samples are : 109g and 192g
∆T= 30.1-21=8.9°c.
The heat of the samples are for 109g are:
0.109 × 4186 × 8.9 =4060.84J
For 0.192g are;
∆T= 67-30.1-=36.9°c
0.192 × 4186×36.9=29656.97J
Answer:
90 J
Explanation:
W=fd
W=(75)(1.2)
W= 90 J
Is this practically possible? How can a 100kg man fly? Hahaha
Answer:shorter higher
Explanation:Compare to visible light, the wavelength of X-rays is shorter and then frequency is higher
