Answer:
Angle of incline is 20.2978°
Explanation:
Given that;
Gravitational acceleration on a planet a = 3.4 m/s²
Gravitational acceleration on Earth g = 9.8 m/s²
Angle of incline = ∅
Mass of the stone = m
Force on the stone along the incline will be;
F = mgSin∅
F = ma
The stone has the same acceleration as that of the gravitational acceleration on the planet.
so
ma = mgSin∅
a = gSin∅
Sin∅ = a / g
we substitute
Sin∅ = (3.4 m/s²) / (9.8 m/s²)
Sin∅ = 0.3469
∅ = Sin⁻¹( 0.3469 )
∅ = 20.2978°
Therefore, Angle of incline is 20.2978°
Answer:
b) the specific location of the charged particle A
f) the distance between the point charge Q and the charged particle A
Explanation:
For this exercise we write the electric field
E = k Q / r²
where r is the distance between charge Q and test charge A
Let's examine the different claims
a) do not depend. The charge of the individual is independent of the elective field
b) depends. The position of the particle is different if it has the same distance
c) do not depend. The particle Q must be considered the origin of the coordinate system
d) does not depend. The charge of a particle is independent of the field where it is
e) does not depend. The position of the particle is fixed
f) depends. The field is different for each distance
g) does not depend. The amount of electric charge is independent of the field
Answer:A hibernation to lower metabolism in the winter
Explanation:
the others would not be beneficial in the tundra since the tundra is cold adaptations that retain heat would be best
Answer:
Option C
Explanation:
Centripetal acceleration formula regarding velocity and radius is,
now we know the centripetal acceleration is 9 and the radius is 16 so we plug these values into our formula,
so velocity is 12 m/s
Now for the angular velocity, the formula of centripetal acceleration regarding angular velocity and radius is,
we know the centripetal acceleration is 9 and the radius is 16 so plug these values into the formula,
so angular velocity is 0.75 rad/s
