Answer:
P.E = mgh = 120N
Step-by-step explanation:
v² = u² - 2as
At the top, the velocity is = 0
0² = 4² - 2 x 10 x s
4² = 20s
s = 16/20
s = 0.8metres.
It rose only 0.8metres.
Therefore P.E = 15 x 10 x 0.8
:. P.E = 15 * 8
:. P.E = 120N
5(2x + 3y) - 4(3x - 5y)
5(2x) + 5(3y) - 4(3x) + 4(5y)
(10x + 15y) + (-12x + 20y)
(10x - 12x) + (15y + 20y)
-2x + 35y
Answer: A=5/7. B=3/2. C=1/6
D=3/5. E=14/11. G=5/7 H=3/2 I=1/6 j=3/5 K=14/11 L=7/8
Step-by-step explanation:
Considering that it is allowed to repeat the digits in the three-digit code, we have,
10 x 10 x 10 ways
which is equal to 1000 ways.
For the scenario that only even numbers without repetition can be included, we have,
5 x 3 x 1 ways
which is equal to 15 ways.
The probability is therefore 15/1000 or 3/200.
