That the field studys the social context in relationships, society, family, school, etc. The way we form relationships, how society affects the relationships we decide to form, how much society influences our decisions, jobs, education( more than we can imagine.)
I believe the most aggravating issue is the police bruality. The fact that the men who are suppose to be heroes, save lives through enforcing the laws, and give protection to the citizens, are instead acting as criminals themselves killing and creating a sense of danger is inexcusable and a solution needs to be made .

A child with a mass of 20 kg sits at a distance of 2 m from the pivot point of a seesaw. where should a 16-kg child sit to balan

Maksim231197 [3]

In the above problem, we need to find mass of the second child, so that the Center of Mass remains at the origin( pivot).

CM= m1r1+m2r2/m1+m2
0= 20*-2+16*r2/20+16
r2= 40/16
r2= +2.5 m

8. What current flows through a 1.15 kW electric fire at a potential difference of

Vilka [71]

Answer:

I = 5[amp]

Explanation:

Electrical power is defined as the product of voltage by current.

$P=V*I$

where:

P = power = 1150 [W]

V = voltage = 230 [V]

I = current [amp]

Now replacing:

$1150=230*I\\I=1150/230\\I=5[amp]$

A 15 [amp] fuse must be used. Always the fuse must be larger than the operating current, to protect the equipment from very high currents. above 15 [amp]

A cat runs and jumps from one roof top to another which is 5 m away and 3 m below. Calculate the minimum horizontal speed with w

icang [17]

ThIs is the same type of problem
find out the time value
3 = 1/2*a*T^2
6/10 = t^2
t = 0.77 seconds
and the distance is given 5 m
thus speed ,= distance/time
speed = 5/0.77
= 6.45 m/s
