Answer:
We could reduce the force or increase the mass of the object.
Explanation:
Using the definition of force, according to Newton's second law, (F = ma) the acceleration is directly proportional to the force and inversely proportional to the mass. Therefore, if we want to reduce the acceleration of an object we have two options:
- We could reduce the force
- We could increase the mass
In both cases a will decrease.

Answer:
A. quality of road-making material
Explanation:
The CBR method of flexible pavement design gives an idea about the:
A. quality of road-making material
B. traffic intensities
C. characteristics of soil
D. All of the above
The California Bearing Ratio (CBR) test is a penetration test used to evaluate the subgrade strength of roads and pavements. The results of these tests are used with the curves to determine the thickness of pavement and its component layers. it is the measure of the resistance of a material against the penetration of a standard plunger.
This can be used to determine the quality of road making material. CBR is expressed as the percentage of the actual load to the standard load.
Answer:
B.The linear velocity of the gears is the same. The linear velocity is 432π centimeters per minute.
Explanation:
As we know that the small gear completes 24 revolutions in 20 seconds
so the angular speed of the smaller gear is given as
Now we know that the tangential speed of the chain is given as
so we have
Since both gears are connected by same chain so both have same linear speed and hence correct answer will be
B.The linear velocity of the gears is the same. The linear velocity is 432π centimeters per minute.
the answer is ( True ) .
the current is the same in series circuits .
