Answer:
We live in a very adaptable environment. If we cannot adapt to the environment, we will not be able to survive.

In our problem, we know

and

, and using the relationship mentioned above, we can find the mass m of the particle:
' C ' is the only correct statement on the list. We don't know anything about diagram-x or diagram-y because we can't see them.
Answer:
A stripe of magnetic information that is affixed to the back of a plastic credit or debit card.
Answer:
dt/dx = -0.373702
dt/dy = -1.121107
Explanation:
Given data
T(x, y) = 54/(7 + x² + y²)
to find out
rate of change of temperature with respect to distance
solution
we know function
T(x, y) = 54 /( 7 + x² + y²)
so derivative it x and y direction i.e
dt/dx = -54× 2x / (7 +x² + y²)² .........................1
dt/dy = -54× 2y / (7 + x² + y²)² .........................2
now put the value point (1,3) as x = 1 and y = 3 in equation 1 and 2
dt/dx = -54× 2(1) / (7 +(1)² + (3)²)²
dt/dx = -0.373702
and
dt/dy = -54× 2(3) / (7 + (1)² + (3)²)²
dt/dy = -1.121107
