Answer:
70 kg is the mass of the object
Explanation:
This question can be solved with this simple formula:
Weight force = mass . gravity
686 N = mass . 9.8 m/s²
686 N / 9.8 m/s² = mass → 70 kg
Note → 1N = 1 kg . m / s²
Answer:
Speedometer, instrument that indicates the speed of a vehicle, usually combined with a device known as an odometer that records the distance traveled.
Explanation:
Answer:
The equivalent capacitance will be 
Explanation:
We have given two capacitance 
They are connected in parallel
So equivalent capacitance 
This equivalent capacitance is now connected in series with 
In series combination of capacitors the equivalent capacitance is given by 
So the equivalent capacitance will be
No it's the opposite, ths higher the pitch the greater the frequency.
Answer:
240 V
Explanation:
The obvious answer is that if the transformer is connected directly to the motor (with no intervening losses), the output voltage of the transformer must match the required input voltage of the motor, 240 V.
__
We're not given, or asked for any other information, so this is all we can say about the connection. Whether a transformer with a 240 V secondary rating is adequate, we have not enough information to say.
