The SI unit of mass is the kilogram, and
the SI unit of force is the Newton.
Answer:A the two wire will attract each other
Explanation:
When current is flowing in a wire it is surrounded by magnetic field whose direction can be given by right hand thumb rule.
If current is in direction of your thumb then wrapping of fingers will give the direction of magnetic field.
If two wires with current in same direction flows then the combined magnetic field will be constructive in nature and thus they attract each other.
force on second wire due to first wire is
which will be towards the first wire
Answer:
Tech B is correct and Tech A is incorrect.
Explanation:
Here Tech A is wrong because when diagnosing an overheating hydraulic system, it is not necessary to un plugg the oil cooler rather it should be plugged to for proper diagnosis.
Technician B says running the hydraulic system at a lower operating temperature will reduce the possibly of oil oxidation is correct statement because at temperature oil's physical as well as chemical property tend to change.
Hence, Tech B is correct and Tech A is incorrect.
Answer:
Weight = 9800Newton
Explanation:
Given the following data;
Mass of car = 1000kg
Acceleration due to gravity = 9.8m/s²
To find the weight of the car;
Weight is given by the formula;
Weight = mass * acceleration due to gravity
Substituting into the equation, we have;
Weight = 1000*9.8
Weight = 9800Newton
