The correct answer is D. 1.55 hm
We need to convert dm to hectometers,
We know that,
1 decimeter = 0.001 hectometers
1 dm = 0.001 hm
Using this conversion we get
(1550 × 1) dm = (1550 × 0.001) hm
1550 dm = 1.55 hm
It means 1550 dm can expressed as 1.55 hectometers.

Answer:
15
Explanation:
If you have to go back from the northern position to the first position, you have to replace yourself a second time by 5 miles. Then you just need to add 5 again for the south.
The craft is moving at a speed of v = 0.024c or around 7 million metres per second or 16 million miles per hour.
The time dilation factor is equal to 3600/3599 if we only want 3599 seconds of the craft's time to pass for every hour (3600 seconds) of Earth time. However, there is a connection as well.
γ = = Dilation factor
Also, γ = 1/ √/
which we can solve algebrically to yield,
= √1-1/γ
we get,
= 0.024
v= 0.024c
Accordingly, the craft is moving at a speed of v = 0.024c, or around 7 million metres per second or 16 million miles per hour.

Answer:
0.324×10⁻³ m/s²
Explanation:
G=Gravitational constant=6.67408×10⁻⁸ m³/kg s
m₁=m₂=Mass of the ships=42000×10³ kg
r=Distance between the ships=93 m
The ships are considered particles
From Newtons Law of Universal Gravitation
∴Acceleration of one of the liners toward the other due to their mutual gravitational attraction is 0.324×10⁻³
Answer:
To keep from falling at the top;
M V^2 / R = M g
This can be rewritten
1/2 M V^2 = M g R /2
2 M g R = 1/2 M V^2 difference in KE between top and bottom
2 M g R + M g R / 2 = 5/2 M g R
Adding the minimum KE at the top to the KE gained when the potential energy of 2 M g R is converted to KE
