By what i know i think that the answer would be A a homogeneous mixture.
Carbon is the answer. IF oxygen were on the list it would also be correct but for this its Carbon<span />
Answer:
Δ v = 125 m/s
Explanation:
given,
mass of space craft = 435 Kg
thrust = 0.09 N
time = 1 week
= 7 x 24 x 60 x 60 s
change in speed of craft = ?
Assuming no external force is exerted on the space craft
now,
a = 2.068 x 10⁻⁴ m/s²
using equation of motion
Δ v = a t
Δ v = 2.068 x 10⁻⁴ x 7 x 24 x 60 x 60
Δ v = 125 m/s
The tension in the string corresponds to the gravitational attraction between the Sun and any planet.
Answer:
Explanation:
Given
Radius of A is twice of B i.e.
Also Potential of both sphere is same
thus
(b)Ratio of
Electric Field is given by
thus ----1
----2
Divide 2 by 1
