In option A there are two resistors in which two terminals of resistors are connected with the terminals of battery so here they are connected in parallel.
In option B all resistors and battery is connected in a single loop so it is a series combination of all.
In option C all three resistors are connected by their terminals to a single battery so here all three resistor are in parallel with the battery.
In option D only one resistor is connected in series with a battery as one single loop is there.
So in the above all cases two resistors are in parallel with battery in option A

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
Complete Question
A wave is described by y(x,t) = 0.1 sin(3x + 10t), where x is in meters, y is in centimetres and t is in seconds. The angular wave frequency is
Answer:
The value is 
Explanation:
From the question we are told that
The equation describing the wave is y(x,t) = 0.1 sin(3x + 10t)
Generally the sinusoidal equation representing the motion of a wave is mathematically represented as

Where w is the angular frequency
Now comparing this equation with that given we see that

Answer:
??
Explanation:
what's the actual question
Answer:
impulse = 8820 kg·
or 8820 N·s
Explanation:
Impulse J is equal to the average force
multiplied by the elapsed time Δt or in equation form, J =
Δt
As long as your force of 450 N is constant then that value is your average force
and your elapsed time is 19.4 seconds.
Multiply these values.
You will get an impulse of 8820 kg·
or 8820 N·s.
