The whole question isn't shown so we cant answer it.
Answer:
The right option is the 'polar' option.
Explanation:
- The right answer cannot be ionic as sharing of electrons is mentioned. Ionic bonds don't involve the sharing of electrons
- Polarity in terms of bonding is used to describe the situation when one of the atoms involved in the sharing of electrons is more electronegative than the other and pulls the shared electrons more towards itself, thereby inducing a slight positive charge on the other atom and gaining a slight negative charge itself.
- In the absence of this kind of scenario in a covalent bonding that sharing occurs, then it is described as non polar. The two atoms that participate in the sharing of electrons here have similar electronegativities and thereby leave the shared electrons at the middle.
- Dipolar compound is used to refer to organic molecules that are essentially neutral but carry a positive & negative charge in one of their various existence forms.
Answer:
t = 0.2845Nm (rounded to 4 decimal places)
Explanation:
The disk rotates at a distance of an arc length of 28cm
Arc length = radius × central angle × π/180
28cm = 10cm × central angle × π/180
Central angle = 
× 180/π ≈ 160.4°
Torque (t) = rFsin(central angle) , where F is the applied force
Radius in meters = 10/100 = 0.1m
t = 0.1m × 16N × sin160.4°
t = 0.2845Nm (rounded to 4 decimal places)
Answer:
10000N
Explanation:
Given parameters:
Mass of the car = 1000kg
Acceleration = 3m/s²
g = 10m/s²
Unknown:
Weight of the car = ?
Solution:
To solve this problem we must understand that weight is the vertical gravitational force that acts on a body.
Weight = mass x acceleration due to gravity
So;
Weight = 1000 x 10 = 10000N
