a and b are dimensionally homogenous but c and d aren't.
Force = N (newtons) = kg * m/s^2
Therefore,
a) F = m* a = kg m/s^2 (since m (mass) = kg and a (acceleration)= m/s^2) = kg m/s^2
b) F = m*(v^(2)/r)= kg * ((m/s)^(2)/m) = kg m/s^2 = kg m/s^2
c) F = m * (v2-v1)= kg * (m/s - m/s) = kg m/s ≠ kg m/s^2
d) F= m * v = kg * m/s ≠ kg m/s^2
Hope this helps
Answer:
160
Step-by-step explanation:
Is means equals and of means multiply
24 = 15% * N where N is the unknown number
Change to decimal form
24 = .15 N
Divide each side by .15
24/.15 = .15N/.15
160 = N
Answer:
(x, y) ⇒ (x -2, y +2)
Step-by-step explanation:
Reflection across the line y = x+2 has the effect of interchanging x and y and translating by (-2, 2).
Reflection across the line y = x+4 has the effect of interchanging x and y and translating by (-4, 4).
The composition of these transformations is then ...
(x, y) ⇒ ((x +2) -4, (y -2) +4) = (x -2, y +2)
The solution of the inequality is x < -9
<h3>How to solve the inequality for x?</h3>
The inequality expression is given as:
-11 < -18- 7/9x
Add 18 to both sides of the inequality
18 - 11 <- 7/9x
Evaluate the difference
7 <- 7/9x
Multiply both sides by -9/7
-9 < x
Rewrite as:
x < -9
Hence, the solution of the inequality is x < -9
