From Hooke's law the spring constant k is given by F = ke; then k = F/e. But F = Ma = Mg = 10 * 9.8 = 98N where g = 9.8ms^(-2) Extension e = 2cm = 0.02m. So k = 98/0.02 = 4900 N/m.

Answer:
How much cash is expected for payments on account in June? = $412,400.
Explanation:
Cash Required for expected payments on account in June
Pilsner Inc. pays 25% on account in the month of billing and the remaining 75% in the next month, therefore, for the month of June the total payment will include 75% of Purchases made in May and 25% of purchases made in June.
Purchases in May = $411,200
Purchases in June = $416,000
Total Payment for May = (75% of 411,200)+(25% of 416,000)
= $308,400 + $104,000
= $412,400.
There are 720kcal of fat in the cake.
<h3>How to illustrate the information?</h3>
It should be noted that from the information given, Sarah is making a pound of cake for the cake sale. Of the 2400 kilocalories for the entire cake, 30% comes from fat.
Based on the information, it should be noted that one simply has to multiply the percentage by the total calories that are given. This will be calculated thus:
Number of calories that are fat = Percentage × Total calories
Number of calories that are fat = 30% × 2400
Number of calories than are fat = 0.3 × 2400
= 720
Therefore, there are 720kcal of fat.
