Answer:
0.088 seconds
0.0880000273785 second
0.08800054757 seconds
Explanation:
In the question it is given each century adds 1 ms to a day due to the slowing rotation of the Earth
In 88 centuries the length of the first day of the year will be
88 × 1 = 88 ms = 0.088 seconds
1 ms = 1 century
1 century = 100 years × 365.25 days
⇒1 ms = 36525 days
Sum of the gain on the first day would be
0.088 + 2.7378×10⁻⁸ = 0.0880000273785 second
Sum of the gain on the second day would be
0.088 + 2.7378×10⁻⁸+2.7378×10⁻⁸ = 0.08800054757 seconds
Velocity is made of speed and direction. Around a circular track, direction is constantly changing, so velocity is too. This is one form of acceleration.
Answer:
<h2>R = 3.6Ω</h2>
Explanation:
Before we can calculate the resistance of the wire, we need to first calculate the Force experienced by the wire in the magnetic field. The force experienced by the wire is expressed as;
F = BIL
B is the magnetic field measured in Tesla = 4.8T
I is the current in the wire
L is the length of the wire = 2m
F is magnetic force acting on the wire = 8N
from the formula I = F/BL
I = 8/4.8*2
I = 8/9.6
I = 0.83Amperes
According to ohms law;
V=IR
R = V/I
given Voltage = 3V
R = 3/0.83
R = 3.6Ω
The resistance of the wire to nearest tenth is 3.6Ω to nearest tenth
Answer:
The correct option is : B. stagnation
Explanation:
Air mass is a volume of air, which is described on the basis of water vapor content and temperature. It has the ability to adapt to the characteristics of surface below it and can travel thousands of miles from its source region.
An ideal source region of an air mass must fulfill the following two criteria:
1. It should be a large and uniform area.
2. the area should have stagnant circulation of atmospheric air .
Answer:
Explanation:
Given:
- mass of the object,
