Answer:
F = 0.114 N
Explanation:
a) The magnetic force is given by the equations
F = q v x B = I Lx B
the bold incate vector. This equation can be used in the form of magnitude and find the direction separately with the rule of the right hand
F = i L B sin θ
Where θ is the angle between the direction (L) and the magnetic field, if the two are perpendicular sin 90 = 1
Let's calculate
F = 3.30 0.127 0.272
F = 0.114 N
b) to know the direction of the magnetized field we must know the direction of B and L, but in the problem they tell us that they are perpendicular, but not the direction of each
Answer:
1. the principle of original horizontality
2. the principle of crosscutting relationships
3. the law of superposition
4. older
5. younger
Absolutely false!! Creativity, curiosity encouraged in Scientific endeavors. Science is all about exploring knowledge, it just promotes intelligency!
In Short, Your Answer would be "False"
Hope this helps!
Air blows from one place to another because gases move from high-pressure areas to low-pressure areas
In simple words
it happens because of pressure differences.
Explanation:
Given that,
Mass if the rock, m = 1 kg
It is suspended from the tip of a horizontal meter stick at the 0-cm mark so that the meter stick barely balances like a seesaw when its fulcrum is at the 12.5-cm mark.
We need to find the mass of the meter stick. The force acting by the stone is
F = 1 × 9.8 = 9.8 N
Let W be the weight of the meter stick. If the net torque is zero on the stick then the stick does not move and it remains in equilibrium condition. So, taking torque about the pivot.
W = 3.266 N
The mass of the meters stick is :
So, the mass of the meter stick is 0.333 kg.
