The term “good mother dinosaurs” is a term given to a type of dinosaur called Maiasaura which lived in the Upper Cretaceous Period, about 76.7 million years ago. This term is given<span> to the Maiasaura because of the meaning of its name "Maia". This name means "good mother" because this type of dinosaur found near of the nest of eggs and embryos.</span>
(a) The initial speed at which the bottles are launched is 4.27 m/s.
(b) The horizontal displacement at which the bottle land is 1.75 m.
<h3>Initial speed of the bottle</h3>
The initial speed of the bottle is calculated as follows;

where;
- T is time of flight
- u is the initial speed
2usinθ = Tg
u = Tg/(2sinθ)
u = (0.5 x 9.8)/(2 x sin35)
u = 4.27 m/s
<h3>Horizontal displacement of the bottle</h3>
X = u²sin(2θ)/g
X = (4.27² x sin(70))/(9.8)
X = 1.75 m

Answer:
Number of electrons, n = 395.47
Explanation:
It is given that,
Force between two spheres, 
Distance between spheres, r = 35 cm = 0.35 m
A force of repulsion is acting on the spheres. It is given by :





Let n is the number of electrons on the spheres. So,
q = n e


n = 395.47
So, the the number of excess electrons on the spheres are 395.47. Hence, this is the required solution.
Answer:
A. Net force is 15 N.
B. The answer is given below.
Explanation:
The following data were obtained from the question:
Force applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 NForce applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 N
Net force (Fₙ) =?
A. Determination of the net force.
Force applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 N
Net force (Fₙ) =?
Fₙ = Fբ – Fᵧ
Fₙ = 30 – 15
Fₙ = 15 N
Thus, the net force acting on the box is 15 N.
B. From the question given above, we can conclude that the box will move towards you because the force applied by your friend is greater than yours.
