A charge is moving downwards so let say this downwards direction is along -z direction
Also here magnetic field is given towards left so let say left direction is towards -x direction
now we have to find force direction so as we know that force on a moving charge is given by
so here we have
so force is along +Y direction
Hi there!
The formula for velocity given acceleration:
v = at
Plug in given values:
v = 6.4(7) = 44.8 m/s
Answer:
True
Explanation:
Distance is defined as the length of the actual path traveled by the body.
Displacement is defined as the minimum distance between the two points.
the magnitude of displacement is always less than or equal to the distance traveled by the body.
As a deer runs from A to b , so it means the distance traveled by the deer is either equal to the magnitude of displacement or always greater than the magnitude of displacement of the deer.
Displacement can never be greater than the distance.
Thus, the option is true.
R=ρ l/a
l=5 cm
a=0.10 cm²
ρ=1.77×10∧-6 Ωcm
R=(1.77×10∧-6) ×5/0.10
=8.85 ×10∧-5 Ω
resistance is directly proportional to length and inversly proportional to area of cross section is given by above equation
The mass has changed because a gas has formed and left the mixture.
Answer: Option A
<u>Explanation:
</u>
According to law of conservation of masses which is followed by every chemical reaction, the sum of masses of the reactants equal to the sum of the masses of the products. But in this case of baking soda of 10 g reacting with 100 g of vinegar is giving a resulting mixture of 105 g.
So, this mismatch in the resultant mass of the product with the sum of masses of the reactants is due to the formation of bubbles in the chemical reaction between baking soda and vinegar. This gas bubbles formed on reaction of vinegar with baking soda will leave the mixture.
As we known from conservation of mass, the resultant mixture should be equal to the sum of mass of vinegar and baking soda reacted which would have been equal to 110 g ( baking soda 10 g +100 g of vinegar). But we have obtained only 105 g of resultant mixture so the remaining 5 g has been converted into gas and left the mixture.
