The tension in the string an instant before it broke is; T = 0.86 N
<h3>What is the Tension in the string?</h3>
We are given;
mass of ball; m = 60 g = 0.06 kg
Length of string; L = 70 cm = 0.7 m
Height the ball reaches; h = 150 cm = 1.5 m
From Newton's equation of motion;
v² - u² = 2as
where v = 0 m/s Thus;
-u² = 2(-9.81 * (1.5 - 0.7)
u² = 15.696
u = √15.696
u = 3.17 m/s
Thus, tension is;
T = mu²/L
T = (0.06 * 3.17²)/0.7
T = 0.86 N

D. Prefix “pseudo” means “false” or “unreal”
There are different kinds of expression. The expressions that is equivalent to 4r + 3s - 2r is 2r +3s.
<h3>How do you solve from Expression to equivalent?</h3>
Equivalent expressions are known to be any kind of expressions that does the same thing even if they may have different looks.
Note that two algebraic expressions are said to be equivalent, when the two expressions do have the same value in terms of value(s) and variable(s).
Thus in 4r + 3s - 2r, we collect like terms:
4r -2r -3s
=2r-3s
Therefore, the answer is 2r-3s
