For a current-carrying wire running perpendicular to a magnetic field, the magnetic force acting on the wire is given by:
F = ILB
F = magnetic force, I = current, L = wire length, B = magnetic field strength
Given values:
F = 0.60N, L = 1.0m, B = 0.20T
Plug in and solve for I:
0.60 = I(1.0)(0.20)
I = 3.0A
Answer:
By applying a force of one Newton, one can hold a body of mass of 102 gram.
Explanation:
- Force is the pull or push of an object. It can be mathematically measured as, F= m* g.
where, F= force in newton
m= mass in kg
g= acceleration due to gravity (
)
F= m* 9.8
or, m= 
= 0.102 kg
or, m= 102 gram.
- Hence, 102 gram mass can be hold by one Newton force.
Answer: The three causes of demand elasticity are measured by looking at the relative change in demand as it responds to a change in price. How does the total expenditures test help determine demand elasticity? By finding out what the total expenditures are for a product, a business is able to determine the demand elasticity.
If an object experiences no net force, its velocity will remain constant. The object is either at rest and the velocity is zero, or it moves in a straight line with a constant speed.
Answer:
In an exothermic reaction the energy gained by the surroundings must be <u>equal to</u> the energy lost by the reaction.
Explanation:
Exothermic reactions occur by the loss of energy in the form of heat to the surroundings (apparatus and the system).
The heat gained can be quantitatively analysed and measured provided no product escapes the system and it is numerically equal to the amount of heat lost by the reaction.
