Answer:C
Step-by-step explanation: Current electricity is caused by flowing negatively charged particles. The negatively charged particles that are responsible for the flow of electricity are called electrons.
The force is equal at all points in the field as the field lines are parallel in a uniform field. So, negatively charged particles will move in the opposite direction to the current.
Hence, the correct answer is "C. It is caused by flowing negatively charged particles."
Answer:
The Total distance she travel fro work is 30 miles .
Step-by-step explanation:
Given as :
the total time taken to cover distance = 45 minutes
Let The total distance cover = D miles
The distance cover at the speed of 32 mph = 
miles
The time taken to cover miles distance = 
hour
Distance = Speed × Time
∴ = 32 mph × h
or, = 16 miles
Again ,
The distance cover at the speed of 56 mph = 
miles
The time taken to cover miles distance = 
hour
∴ = 56 mph × h
or, = 14 miles
So , The total distance she travel for work = +
Or, The total distance she travel for work = 16 miles + 14 miles = 30 miles
Hence The Total distance she travel fro work is 30 miles . Answer
Answer:
f(− 3) = 84
Step-by-step explanation:
Given the function, f(x) = 7(9 − x), to find the value of f(-3) substitute x = -3 into the function:
f(− 3) = 7(9 − (− 3))
f(− 3) = 7(9 + 3)
f(− 3) = 7(12)
f(− 3) = 84
Therefore, f(− 3) = 84.
