Answer:
I think beach volleyball is a dual sport.
Answer:
6000 N toward west
Explanation:
F = ma
a = 30-15/10 = 1.5 m/s^2 towards west
m = 4000 kg
F = 4000 x 1.5 = 6000 N towards west
Answer:
A. Is the one that the experimenter manipulates directly
Explanation:
The independent variable is the one that is manipulated during an experiment by the experimenter.
The dependent variable is the one that is effected by the independent variable in an experiment.
Answer:
option (a)
Explanation:
There are some properties of charge given as
(a) Charges are of two types: negative charge and positive charge.
(b) Like charges repel each other and unlike charges attract each other.
(c) charges are conserved in nature.
(d) charges are quarantined.
So, the two charges which are opposite in nature can only attract each other.
So, if there is one negative and one positive charge, they always attract each other.
The force of attraction or repulsion between the two charges is given by the Coulomb's law.
Answer:
Explanation:
The constant speed means that ball is not experimenting acceleration. This elements is modelled by using the following equation of equilibrium:
Now, the exerted force is:
The volume of a sphere is:
Lastly, the force is calculated:
