When driving on roads that may be slippery, do not make any sudden changes in speed or direction. Option D is correct.
<h3 /><h3>What is a slippery surface?</h3>
The slick road sign serves as a warning. When the road is wet or ice, drivers should use extra caution and reduce their speed. When the weather is bad, avoid making any rapid changes in direction.
When driving on roads that may be slippery, do not make any sudden changes in speed or direction. It may cause accident because the vehicle can lose their balance.
Hence, option D is correct.

Answer:
See below
Explanation:
rho = R A/l R = resistance A = cross sectional area l = length
<span>In general the larger the pore space (the higher the porosity) the easier it is</span>
The apple is lifted by 1.1 m
<u>Explanation</u>:
- Given that, mgh = 2 J and mass of apple = 180g
- Step 1: convert grams to kg as work is given in SI units.
180 g = 0.18 kg
- Step 2: substitute in the formula for work done.
0.18 * 10 * h = 2
- Step 3: calculate the value of h from this formula.
h = 2/1.8
h = 1.11 m
The volume of the tire at the given diameter and thickness of tube is determined as 1,128.2 cubic inch.
<h3>What is volume?</h3>
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
<h3>
Volume of the tire</h3>
The volume of the tire is the measure of the product of area and thickness of the tire.
The volume of the tire is calculated as follows;
Radius of the tire = 0.5 x 26" = 13"
Volume of the tire = Area x thickness
Volume of the tire = πr² x h
where;
- r is the radius of the tire
- h is the thickness of the tube
Volume of the tire = π(13)² x (2.125)
Volume of the tire = 1,128.2 cubic inch
Thus, the volume of the tire at the given diameter and thickness of tube is determined as 1,128.2 cubic inch.
