Answer:
For vector u, x component = 10.558 and y component =12.808
unit vector = 0.636 i+ 0.7716 j
For vector v, x component = 23.6316 and y component = -6.464
unit vector = 0.9645 i-0.2638 j
Explanation:
Let the vector u has magnitude 16.6
u makes an angle of 50.5° from x axis
So 
Vertical component 
So vector u will be u = 10.558 i+12.808 j
Unit vector 
Now in second case let vector v has a magnitude of 24.5
Making an angle with -15.3° from x axis
So horizontal component 
Vertical component 
So vector v will be 23.6316 i - 6.464 j
Unit vector of v 
Answer:
new temperature of the tire will be 278.76 K
Explanation:
when the temperature increases, the particles will have greater kinetic energy and also the pressure will be increase for the gas particles.
so when the temperature increases, pressure will also increase and vice versa
T is directly proportional to P
T1 = initial temperature= 303 k
P1= Initial pressure = 325000 pa
T2= Final temperature= ?
P2= Final pressure = 299000 pa
mathematically
P1/T1= P2/T2
T2= P2 x T1/P1
T2 = 299000 x 303/ 325000= 278.76 k
Answer:
92.397amu
Explanation: The exact amu of the mystery element is obtained by multiplying the relative abundance of each individual isotope by its respective amu and then summing the results.
The sum of the total relative abundance for all the isotopes should be 100%.
However, the relative abundance of the isotope with 95.502amu is not given; therefore to obtain it we subtract the sum of the known relative abundances from 100% as follows:
Relative abundance of isotope with 95.502amu = 100-(23.63+30.53) = 42.84%
