Answer:
Explanation:
For a charged particle moving perpendicularly to a magnetic field, the magnitude of the force exerted on the particle is:
where
q is the magnitude of the charge of the particle
v is the velocity of the particle
B is the magnetic field strength
In this problem, we have
is the charge of the electron
is the velocity
is the magnetic field
Substituting into the formula, we find the force:
Answer:
= 51° West of North
Explanation:
The displacement along the horizontal direction
The displacement along the vertical direction
The magnitude of the displacement is
The direction is
= 51° West of North
Answer:
1) A trait is a specific feature or characteristic, typically genetic.
2) One trait that helps an animal survive is a Chameleon's camouflage. Camouflage helps the chameleon blend in with their surroundings to avoid a predator or to sneak up on prey.
Explanation:
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect on planets.
Answer:
The correct answer is option 'd' : a billboard on the side of a road.
Explanation:
We know that when we are in an moving object it seems to us that we are at rest and our surroundings are moving, this is the concept of relative motion.
We can observe speed of different things relative to other things weather they are moving or are at rest. In order to measure speed of an object we have to measure it with respect to a frame of reference and this frame is in which the observation of the speed shall be taken. This frame can be at rest or can be moving at any speed.
In our case
1) when we are travelling in the car if we observe the plane we will see the plane moving with a speed while it would not be possible to determine our own speed.
2) If we observe a car travelling next to us at the same speed we will observe it to be not moving at all or it shall be at rest with respect to us.
3) If we observe a car traveling next to you at a faster speed than we are travelling we shall observe that it goes past us but at a slower speed.
4) If we observe a billboard at the side of a road since it is at rest with respect to the ground we shall get an idea about how fast we are moving.
