Step-by-step explanation:
1/4x1=1/4
0x1/4=0
-1x1/4=-1/4
-2x1/4=-1/2
Very easy
Answer:
F= G m₁m₂/r²
a. F is directly proportional to the masses so any increase in the masses will increase the Force F and vice versa.
b. F is inversely proportional to the square of the distance between the masses so any increase in the distance will decrease the force F and vice versa.
c. G is a gravitational constant and is expressed in Nm²/kg². this will give force in Newtons
Solution: X=9.5
Explanation: x-5.5=4 —> x=4+5.5 —> x=9.5

60000
Step-by-step explanation:
70000 - 10000 = 60000
Answer:
6108795
Step-by-step explanation:
To obtain the number of ways the committee can be selected :
4 teachers from the 12 teachers available and 3 students from the 43 students available
Using combinatorics :
12C4 * 43C3
recall :
nCr = n! ÷ (n - r)!r!
Using calculator :
12C4 = 495
43C3 = 12341
12C4 * 43C3
495 * 12341
= 6108795
