HELP!!! HURRY DUE BY 4:30!!!
Ipatiy [6.2K]
Work = force * distance. 
<span>You must produce twice as much energy as we are lifting the weight twice as high. </span>
<span>But because you aren't increasing the force, you need to increase the length of the ramp instead. </span>
<span>The new length will be twice as great as the previous length. </span>
<span>So 8 metres is required. </span>

Hope this helps.

A patient is given 40.00 mg of iodine-131 (131I ) 131 53
N76 [4]
<h3>Answer:</h3>

2.5 mg

<h3>Explanation:</h3>

<u>We are given</u>;

  • Original mass of I-131 is 40.0 mg
  • Half life of I-131 is 8 days
  • Number of days 32 days

We are required to determine the mass that will remain;

  • Using the formula;

N = N₀ × 0.5^n

where, N is the remaining mass, N₀ is the original mass, and n is the number of half lives.

Therefore;

n = time ÷ half life

   = 32 days ÷ 8 days

  = 4

Therefore;

Remaining mass = 40.0 mg × 0.5^4

                            = 2.5 mg

Hence, the remaining mass of I-131 after 32 days is 2.5 mg
