Answer:
$69.35
Explanation:
125 divided by 3.785(liters in a gallon) , you get 33.025
multiply 2.1 by 33.025 and you will get $69.35
Answer:
C. Gamma > beta > alpha
Explanation:
<u>Alpha rays</u> : These are positively charged and have mass 4u. These contain high energy Helium nucleus with 2 proton and 2 neutron.
These are heavier and maximum charged than beta and gamma particles.They have low velocity,least penetration power (can't travel more than 10-18 cm).
<u>Beta rays</u> : They are negatively charged and have negligible mass.
On emmission of beta particle, neutron is divided into proton and electron. They have less mass and very high velocity, so their penetrating power is more than alpha particles.
<u>Gamma rays</u>: These are parts of electromagnetic spectrum and travel with the speed of light (maximum velocity).Gamma rays do not have mass have maximum penetrating power.

Answer:
The answer to your question is : 16.9 g of Ag
Explanation:
Data
26 g Ag
10.8 g of Sn
2.4g Cu
0.8 Zn
Ag = ? in 26 g of sample
Total mass in the amalgam = 26 + 10.8 + 2.4 + 0,8 = 40 g
Rule of three
40 g of sample -------------- 26 g of silver
26 g of sample -------------- x
x = (26 x 26) / 40
x = 16.9 g of Silver
