Explanation:
what is the force
ican't under stand these question
Answer:
2.5m/s²
Force = mass x acceleration
Explanation:
Given parameters
Mass = 200kg
Force = 500N
Unknown:
Acceleration = ?
Solution:
According to the Newton's second law of motion "the constant force applied on a massive body causes it to accelerate".
Mathematically;
Force = mass x acceleration
Now insert the parameters and solve;
Acceleration =
Acceleration =
= 2.5m/s²
Answer:
1. C
2. D

Step one:
given
frequency =512 Hz
The speed of sound is 340.0 m/s.
Required
The wavelength
Step two:
the formula for wavelength is


substitute the given data

Explanation:
This how you do it..
Calculate Watt-hours Per Day. Device Wattage (watts) x Hours Used Per Day = Watt-hours (Wh) per Day. ...
Convert Watt-Hours to Kilowatts. Device Usage (Wh) / 1000 (Wh/kWh) = Device Usage in kWh. ...
Find Your Usage Over a Month.
