Answer:
continuous change in position with respect to time
Explanation:
Velocity is defined as the rate of change of the position of an object with respect to its time.
It's the vector quantity of speed as it has both magnitude and direction.
Hope this helps :)
Answer:
c. Rock, metal, and ices made of materials like water, ammonia, and methane condensed into a solid and grew large enough to gravitationally attract hydrogen and helium gas from the Solar Nebula.
Explanation:
Given the information about dependence of planetesimal composition on distance from the Sun and the existence of the frost line resulted in two main types of planets in our Solar System: the inner rocky planets and the outer gas giants. I have learned that planetesimal formation through accretion, and the types of materials that condensed at that distance from the Sun, will lead to the formation of Rock, metal, and ices made of materials like water, ammonia, and methane condensed into a solid and grew large enough to gravitationally attract hydrogen and helium gas from the Solar Nebula.
The angle is 34.4°.
The radius of a circle and the central angle determine the length of an arc. We are aware that the arc length is equivalent to the circumference for an angle of 360 degrees (2π). As the proportion between angle and arc length is constant, we can say that:
L / θ = C / 2π
As circumference C = 2πr,
L / θ = 2πr / 2π
L / θ = r
We find out the arc length formula when multiplying this equation by θ:
L = r * θ
The arc length is equal to the radius multiplied by the central angle.
Radius of the circle, r = 2.70m
Length of the arc, L = 1.60 m
L = rθ
θ = L / r
= 1.60 / 2.70
= 0.6 rad
θ = (0.6 rad × 180° ) / π rad
= 34.4°
Therefore, the angle is 34.4°.

B because it’s the answer
Speed of the black Mamba = 18 km/h = 5m/s
now the distance that black mamba cover to catch prey
Now it returns to its hide in 12 s
so average speed of return is given as
Part b)
For the whole trip we know that displacement of the mamba is zero
so average velocity of whole trip will be zero
Part c)
For average speed we know that total distance of the black mamba
d = 12.5 + 12.5 = 25 m
total time taken = 2.5 + 12 = 14.5 s
now average speed is given as
