1. Answer;
Force = 98.1 Newtons
Explanation;
-On the hanging mass the net force is
Fnet = Mh*g - T = Mh*a where Mh is the mass = 10kg, g = 9.81m/s², and T the tension in the string. Its acceleration is a ( same as g)
Thus; Force = 10 kg × 9.81 m/s²
= 98.1 Newtons.
2. Answer;
a = 4.905 m/s²
Solution;
-We know that that T = Ms*a, but Fnet = Mh*g - T = Mh*a
Substituting; T with Ms*a
Mh*g - Ms*a = Mh*a
Mh*a + Ms*a = Mh*g
a = Mh*g/(Mh + Ms)
= 10.0kg*9.81 m/s²/(10kg + 10kg)
= 4.905 m/s²
Answer:
17160
Step-by-step explanation:
first there are 13 options
then there are 13 - 1 that was chosen
then there are 13 - 2 that were chosen
then there are 13 - 3 that were chosen
so that's 13 options, then 12 options, then 11 options, and then 10 options
and in order to figure out all of the possibilties we mutiply the options so
13*12*11*10 = 17160
little further explaining of why this works:
we have a set of letters (3 in a set)
A B C
what are the possible combinations?
AB
AC
BC
BA
CA
CB
the answer is 6 which is also 3 * 2 * 1 = 6
HOPE THAT HELPS!1! ^_^
First choice, given y = mx+b when m is the slope so the slope is 3 for all equations.
The missing number in the given data that has a mean of 79 is: 60.
<h3>How to Find the mean of a Data?</h3>
The mean of a data set is simply the average, that is, it is the sum of all data values divided by the number of data values.
Let x represent the missing number in the data. If the mean is 79, we would have the following:
(89 + 74 + 92 + 80 + x)/5 = 79
(335 + x)/5 = 79
335 + x = 5(79)
335 + x = 395
x = 395 - 335
x = 60
Missing number is: 60.
