Answer:
Explanation:
They are infrared waves which mean they take the form of heat.
Answer:
The magnitude of a uniform electric field that will stop these protons in a distance of 2 m is 1.01 x
N/C
Explanation:
given information,
kinetic energy, KE = 3.25 x
J
proton's mass, m = 1.673 x
kg
charge, q = 1.602 x
C
distance, d = 2 m
to find the electric field that will stop the proton, we can use the following equation:
E = F/q
= (KE/d) / q , KE = Fd --> F = KE/d
= KE/qd
= (3.25 x
J) / (1.602 x
C)(2 m)
= 1.01 x
N/C
Answer:
V1 = ____0.3______ m/s, V2 = ____-0.3______ m/s,
p1 = ____0.015______ kg m/s, p2 = ___-0.015_______ kg m/s,
ptotal = _0___________ kg m/s
Explanation:
Taking the marble ball that moves from right to left as Marble 1 and the one that moves from left to right as Marble 2. We take direction from left to right as negative and from right to left as positive. Therefore, velocity of marble 1 will be +0.3 m/s while velocity of marble 2 will be -0.3 m/s. The mass of marble 1, m2 0.05 Kg and same to marble 2, m2=0.05 Kg
Momentum is product of mass and velocity hence using p to represent momentum
P1=0.05*0.3=0.015 Kg m/s
P2=0.05*-0.3=-0.015 Kg m/s
V1=0.3 m/s, V2=-0.3 m/s
The total momentum before collision will be the sum of P1 and P2 hence 0.015 Kg m/s+-0.015 Kg m/s=0
Ptotal=0 Kg m/s
I think the correct answer would be that there are a relatively small number of moles of HCl present. Dilute would mean that there are very few solute particles dissolved as compared to the solvent particles in the solution. Hope this helps.
