Answer:
a. collectivism
Explanation:
the practice or principle of giving a group priority over each individual in it.
A good example of this is culture. Collectivism in cultural terms refers to a culture that privileges family and community over individuals. For example, children in collectivist societies are likely to take care of elderly parents if they fall ill and will change their own plans in the event of a family emergency.
Yes. It is rather a natural phenomenon. If you search and understand the process of chemical
change or reaction that results to its chemical property outcome, it has a new
formed substance. Unlike physical change or reaction it only changes in shape
or form but the substance, compound or element in the matter is till the same.
Furthermore, when chemical change is undergoing you notice the change in shape,
size and from like the physical change but there is a change in the element,
compound or substance. When you lit a fire on a paper the fire disorients,
disorganizes and disturb the former positions of the atoms and because of the
fire as catalyzer the atoms did its behavior –changing both intrinsic and extrinsic.
Well, you should TAKE COVER UNDER A STUDY DESK, TABLE OR AGAINST AN INSIDE WALL. Which is C. This is because, doing this protects you from the falling objects. If you do A or B, you will probably get crushed by falling objects because you are exposed. Hope I helped.
Answer:
34.4Joules
Explanation:
Complete question
a man is trying to pull a box a distance of 3 m with a force of 20 N that makes a 35º with the horizontal. Find the workdone
Work done = Fdsin theta
Force F = 20N
distance d = 3m
theta = 35 degrees
Substitute
Workdone = 20(3)sin 35
Workdone = 60sin35
Workdone = 34.4Joules
Hence the workdone by the man is 34.4Joules
Answer:
B.)Angular momentum is always conserved
Explanation:
Angular momentum is given by:
where
m is the mass of the object
v is its speed
r is the distance between the object and the centre of its circular trajectory
In absence of external torques, angular momentum is always conserved. That means that for the spinning star, if its radius r decreases (because it shrinks), in order for L (the angular momentum) to be conserved, the speed (v) must increases, therefore the spinning star speeds up.
So, the correct choice is
B.)Angular momentum is always conserved
