The object that reaches the ground first is thebowling ball i think because it weighs heavier but when the tennis ball hits the ground it will bounce again and again till it stops and the bowling ball will just stop it wont bounce
Answer:When the length of a string is changed, it will vibrate with a different frequency.Shorter strings have higher frequency and therefore higher pitch.
Your correct answer would be 0 N
The forces are pulling in opposite directions, therefore they cancel each other out.
Hope that helps!!

Answer:
As per Coulomb's law we know that force between two charges is given as
F = \frac{kq_1q_2}{r^2}F=
r
2
kq
1
q
2
here we know that
q_1 = 2.5 \times 10^{-6} Cq
1
=2.5×10
−6
C
q_2 = -5.0 \times 10^{-6} Cq
2
=−5.0×10
−6
C
r = 0.0050 mr=0.0050m
now from above formula we will have
F = \frac{(9 \times 10^9)(2.5 \times 10^{-6})(5 \times 10^{-6})}{(0.0050)^2}F=
(0.0050)

(9×10

)(2.5×10
−6
)(5×10
−6
)
F = 4500 NF=4500N
so they will attract towards each other as they are opposite in nature with force F = 4500 N
Answer:
a. The acceleration of the bowling ball is 9.5 m/s² toward the center
b. The tension in the rope is 140.24 N
Explanation:
given information:
ball weight, W = 71.2 N
the length of rope, R = 3.30 m
ball speed, v = 5.60 m/s
a. The acceleration of the bowling ball, α
α = 
where
α = the acceleration
v = the speed
R = radius
thus
α =
= 
= 9.5 m/s² toward the center
b. The tension in the rope?
according to the Newton's second law
ΣF = m a
where
F = force
m = mass
a = acceleration
so,
ΣF = m a
T - W = m a
T = m a + W
= (W a/g) + W
= (71.2 x 9.5/9.8) + 71.2
= 140.24 N
