Neptune's largest satellite is Triton, and it revolves in a retrograde orbit, meaning to opposite of Neptune's totation<span />
<span>Since density is equal to mass divided by volume, we can determine the relationship between mass, density, and volume. Therefore, we can automatically know that the answer must either be A or B, since this information is determinable.
The prompt lists the object as small. Therefore, we know that density is high, but volume is low. Let's examine the equation (D = M/V), where d = density, m = mass, and v = volume. In order for any number to be divided by a smaller number and have the end result be a higher number, the numerator (i.e. mass) must be bigger than the denominator (i.e. volume).
We can also see that this is true by substituting in somewhat random numbers for d, m, and v.
D = M / V
5 = 10 / 2
10 > 2
M > V
In conclusion, your answer is D.</span>
Answer:
The distance is 1.4 km.
Explanation:
Given that,
Initial velocity u= 1.7 m/s
Accelerate a= 3.0 m/s²
Time = 30 s
We need to calculate the distance
Using equation of motion
Where, u = initial velocity
a = acceleration
t = time
Put the value in the equation
Hence, The distance is 1.4 km.
Explanation:
C.
Object A will require more force to be set in motion but will travel faster than object B.
2. true
Answer
given,
radius of earth,r = 1.5 x 10¹¹ m
Time,T = 365 days
= 365 x 24 x 3600 s
earth velocity,
v = 3 x 10⁴ m/s
centripetal acceleration of the earth
a = 6 x 10⁻³ m/s²
