Answer
A molecule with seesaw molecular geometry has a bond angle of 90° and 120°.
Seesaw is a type of molecular geometry where there are four bonds attached to a central atom.
Bond is observed in the shape of playground seesaw that is why it is known as a seesaw bond.
Four bonds attached to the central bond formed results as tetrahedral or square planar geometry.
In see-saw, shape maximizes the bond angle of the lone pair and the other atoms in the molecule.
lone pair in the equatorial position offer 120 and 90-degree bond angles whereas bond angle will be 90-degree bond angles if placed at axial position.
Answer:
(a) Time flight is 6.39 s
(b) The range of the projectile is 639 m.
Explanation:
Given;
initial horizontal velocity of the projectile, = 100 m/s
initial vertical velocity of the projectile, = 0
height of the tower, h = 200 m
(a) Time flight is calculated as follows;
(b) The range of the projectile is calculated as follows;
The equation you need to know in order to solve this problem is v=v0+at, where v is final velocity, v0 is initial velocity, a is acceleration, and t is time. Plug in and solve:
30=0+a(8)
30=8a
<em>*Divide both sides by 8*</em>
a=3/75m/s^2
Hope this helps!!
Answer:
the interaction in the protein is greater than the surface with water
\frac{F_i}{F_s} = \frac{\epsilon_s}{ \epsilon_i} \ > 1
Explanation:
The electric force for a charge is
F =
In the exercise indicate that the charge is q and the distance r is maintained, the test charge is another
therefore if we use the index i for the dielectric constant () in the protein
the electric force in water with dielectric constant ()
if we look for the relationship between these forces
therefore the interaction in the protein is greater than the surface with water
Answer:
Car's touch area = 64 m²
Explanation:
Given:
Weight of car = 3,072 N
Pressure = 48 pa
Find:
Car's touch area
Computation:
Area = Force / Pressure
Car's touch area = 3,072 / 48
Car's touch area = 64 m²
