The answer is 2. Beta particle is high energy electrons which is the same mass as positron with little mass. Alpha particle consists of 2 neutrons and 2 protons. Neutrons and protons have almost same mass which is much larger than electrons.
Answer:
<h3>As per Kepler's law we know that </h3>
<h3>\frac{T_1^2}{T_2^2} = \frac{R_1^3}{R_2^3}T22T12=R23R13</h3>
<h3>as we know that for earth the time period is 1 year and its distance is 1 AU</h3><h3>now from above formula we can say</h3><h3>let the time period of Neptune is T and its distance is given as R = 30.06 AU</h3><h3>now we will have</h3><h3>\frac{1^2}{T^2} = \frac{1^3}{30.06^3}T212=30.06313</h3><h3>by rearranging the above equation we have</h3><h3>T^2 = (30.06)^</h3><h3>3T2=(30.06)3</h3><h3>T = 164.8 years</h3><h3>T=164.8years</h3>
<h3>so it will have time period of 164.8 years</h3>
Answer:
Graduated cylinder
Explanation:
A graduated cylinder is used routinely for measuring volume and is considered more accurate than a beaker because of the permanently-marked incremental graduations incorporated in the clear cylinder.
<u><em>PLS MARK BRAINLIEST</em></u>
Answer:
24.5%
Explanation:
You just add up the atomic masses.
Ca - 40.078
Cl2 - 35.4527 x 2 = 70.9054
------ 110.9834
H4 - 1.00794 x 4 = 4.03176
O2 - 31.9998
------ 36.03056
TOTAL - 147.01396
So the water is 36.03056/147.01396 = .245082576 but that is only accurate to three decimals (because the mass of Ca was only given to three decimals) so we write .245 and that is 24.5%
