CuCl2 will have dipole-dipole forces the strongest attraction that will be present. For CuSO4, io- dipole forces would be the strongest and for HF, hydrogen bonding would be the strongest force present. Dipole-dipole are permanent dipoles where two polar molecules interact. For ion-dipole, ions are the contributing factor of such and for hydrogen bonding, it is the bonding of hydrogen atom with a halogen.
Answer:
(B) +18 cm
Explanation:
Given that the distance of the object is infinity.
And the image is formed at a distance of 18 cm, means .
Now as we know that the mirror formula is,
Now put the values of u and v
Therefore the focal length of the mirror is +18 cm.
The digestive system digests and makes nutrients out of food while the circulatory system distributes and circulates the nutrients i believe?
PEG = 0.8*KE.
M*g*h = 0.8 *(0.5*M*v^2) M, h, and v are the vaulter's mass, height, and speed, respectively.
g*h = 0.8*0.5*v^2 Divide both sides by M (the mass).
g*h = 0.4*v^2
(9.81 m/s^2)*h = 0.4*(7 m/s)^2. Note that m and s denote meter and second, respectively.
h = 0.4*(7 m/s)^2 /(9.81 m/s^2) Divide both sides by 9.81 m/s^2. Also, note that m is NOT mass here.
= 0.4*(49 m^2/s^2)/(9.81 m/s^2)
= 0.4*49 m/9.81
Answer = 1.99796 meters
Answer:
Explanation: It would go straight because objects in motion stay in motion and it would stay the same direction
