Answer:
option C
Explanation:
given,
helicopter moving at the speed of = 15 m/s
time before the package hit the ground = 12 s
height above the ground = ?
using the equation
hence, the height above the ground will be approximately equal to 530 m
correct answer is option C
At this temperature, the fever is deemed as mild or a moderate type which is seen as an adaptive response of the body to changes in the environment or the body itself. Bacteria requires high amount of iron and zinc in order to multiply. At this temp., the body makes it less available to have such compounds which would be beneficial to the body.
Answer:
c. Ф increases and E decreases
Explanation:
From Gauss's Law
Ф = Q / ε₀ _____(1)
The electric flux Ф is the surface integral of electric field E
Ф _____(2)
|E| = Q/ 4πε₀r² _____(3)
Where,
Φ is the electric flux through a closed surface S enclosing any volume V
E is the electric field
dA is a vector representing an infinitesimal element of area of the surface
Q is the total charge enclosed within V, and
ε₀ is the electric constant
Considering the relationship between equation 1, 2 and 3, If the charge, Q, is doubled and the radius, r, of the surface is also doubled; the electric flux Φ increases and electric field E decreases. From Gauss law in equation 1, the electric flux Φ is directly proportional to the charge, Q, with ε₀ being a constant. An increase in charge will cause an increase in electric flux. Also, the electric field, will decrease because of the inverse relationship between radius and electric field.
These pattern of lines<span>, sometimes referred to as </span>electric field lines<span>, point in the direction that a positive test charge would accelerate if placed upon the </span>line<span>. As such, the </span>lines<span> are directed away from positively charged source charges and toward negatively charged source charges.</span>
