Answer: HBr is a powerful and dangerous acid
Explanation:
HBr gives hydronium ions () in its aqueous solution and presence of large amount of ions in the solution makes it corrosive in nature. This is because when these ions present in the solution comes in contact with any of the objects they tends to neutralize their charge and due to this action of ions we observe corrosive nature of an acid.
Chemical equation for HBr dissociating into ions is given as:
Hence ,HBr is a powerful and dangerous acid. Where as are gas , basic oxide and salt respectively.
Answer:
767.6 m/s
Explanation:
We consider momentum in both x and y components
Since momentum, p=mv where m denote mass while v is velocity then
In the y direction
3m*288=279m+my
y=585 m/s
In the x direction and taking right as positive then
3m*288=367m+mx
x=497 m/s
The resultant gives the velocity of the third fragment
Answer:
The magnetic field strength required to hold anti-protons, moving at 5.70 ✕ 10⁷ m/s in a circular path of 3.20 m in radius is 0.186 T.
Explanation:
To solve the question we note that the magnetic force on a moving charge is given by
F = q·v·B
Where
q = Charge
v = Velocity of the charge =5.70 ✕ 10⁷ m/s
B = Magnetic field
Based on Newton's second law,
Force = Mass, m × Acceleration, a = m × a
Where:
a = Acceleration
m = Mass of anti-proton = Mass of proton = 1.6726219 × 10⁻²⁷ kg
We note that for circular motion, acceleration a is given by
.
Where:
r = Radius = 3.20 m
Therefore, for the circular motion, force, F =
Equating the magnetic force equation to the circular force equation, we have
= q·v·B So that, we find B by making the subject of the formula as follows
. Which gives
= 0.186 T
The magnetic field strength is
B = 0.186 T
