Answer:
The magnetic field 0.01m from the wire is 0.2T.
Explanation:
The magnetic field at a distance due to a wire carrying current is
Now, let us call the magnetic field at and the magnetic field at :
Dividing by we get
Now we put in the numbers
and to get:
solving for we get:
which is the magnetic field at 0.01 meters from the wire.
Answer:
An unbalanced force means that there are more than one forces with different directions or magnitudes affecting the object. In this case, the vector addition of the forces should be done. The vector addition will result a net force. The object will move in the direction of the net force.
Answer:
The atmosphere and Earth's interior are layered by density. The differentiation between these layers is due to processes that took place during the early stages of Earth's formation (ca. 4.5 billion years ago). At this time, melting would have caused denser substances to sink toward the center while less-dense materials would have migrated to the crust.
Gravity pulls more strongly on denser materials so denser materials are at the center of things. The lowest layer of the atmosphere is denser than the upper layer. Earth's liquid metal oure has convection, which generates the magnetic field.
Explanation:
Gravity pulls more strongly on denser materials so denser materials are at the center of things. The lowest layer of the atmosphere is denser than the upper layer. Earth's liquid metal core has convection, which generates the magnetic field.
The five physical layers are the lithosphere, asthenosphere, mesosphere, outer core, and inner core. Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core.
The layers of the Earth are responsible for the formation of our continents. Earthquakes can be important because of energy (seismic energy) released. The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.
Answer:
56N
Explanation:
Given parameters:
Distance = 40m
Work done = 2240J
Unknown:
Force exerted = ?
Solution:
The work done on a body is the force applied to move a body through a certain distance.
Work done = Force x distance
Now insert the parameters and solve for the force
2240 = Force x 40
Force = 56N
A model train traveling at a constant speed around a circular track has a constant velocity. FALSE.
