Answer:
State vector.
Explanation:
To determine exactly where a satellite is located, engineers must think and calculate positions in three dimensions. A set of data telling engineers all of the various elements of position, velocity, and time for a satellite or spacecraft is known as a state vector.
This ultimately implies that, state vectors gives a detailed description of the position and velocity of a satellite at a specific period of time. Also, the more accurate your input state vector, the more accurate would be the position, velocity and time for a satellite when trying to determine its location. Therefore, the time tag of a state vector shouldn't be too far from the present time of the day.
Answer:
Electric field will be
Explanation:
We have given diameter of the copper d = 2.05 mm
So radius
We know that area
Current is given as i = 4.7 A
So current density
Resistivity is given
We know that electric field is given by
Answer: a convex lens forms a larger virtual image
Explanation: i just took the quiz
Answer:
A bomb that is dropped from a moving helicopter doesn't fall directly downward rather it follows the parabolic path as it were thrown horizontally from a height with certain initial velocity. Therefore, the bomb should be dropped from farther distance equal to the horizontal range before the helicopter reaches above the target.
Answer:
a) 0.09N b) positive x direction
Explanation:
Force on a conductor carrying current in a magnetic field can be expressed as;
F = BILsin(theta) where
F is the force on the conductor (wire)
B is the uniform magnetic field I'm Tesla = 1.8Tesla
I is the current in the wire = 5×10^-2A
L is the length of the wire = 1m
theta is the angle that the conductor make with the magnetic field = 90° (since the wire in the horizontal direction is perpendicular to the field acting upwards)
Substituting this value in the formula to get F we have;
F = 1.8×5×10^-2×1 × sin90°
F = 0.09N
The force on the wire is 0.09N
b) The direction of the force is in the positive x direction since the wire acts horizontally to the magnetic field.
