Greetings!
<span>Six-year-old Fabian likes to fix things with his Dad around the house. He grabs his toy tools and sometimes even picks up a real screwdriver to try and help Dad fix whatever is broken. This is best explained by social learning theory.
The Social Learning theory is a theory of which young children start to learn to do more adult-like things.
Hope this helps!</span>
As per Newton's II law we know that
here for the first case we know that
m = 3 kg
now we will have
now for other case we will have
m = 6 kg
now we have
Answer:
The silk has become negatively charged
Answer:
D. 5.18 x 10⁻¹²
Explanation:
= rate at which sun radiates energy = 3.92 x 10²⁶ W
M = mass of sun = 1.99 x 10³⁰ kg
= rate at which sun's mass is lost
c = speed of light
Energy is given as
E = m c²
Taking derivative both side relative to "t"
= 4.4 x 10⁹ kg/s
t = time interval = 75 yrs = 75 x 365 days = 75 x 365 x 24 hours = 75 x 365 x 24 x 3600 sec = 2.4 x 10⁹ sec
= mass lost
mass lost is given as
m = 10.56 x 10¹⁸ kg
fraction is given as
fraction =
fraction =
fraction = 5.18 x 10⁻¹²
