as it is given that
2.2 lbs = 1 kg
here we know that Megan Progress weighs 130 lbs
so its mass in kg is given as
now to find the weight in Newton unit we can say
so 130 lbs weighs as 579 N in SI units
Answer:
Wavelength = 3.74 m
Explanation:
In order to find wavelength in "metres", we must first convert megahertz to hertz.
1 MHz = 1 × 10⁶ Hz
80.3 Mhz = <em>x</em>
<em>x </em>= 80.3 × 1 × 10⁶ = 8.03 × 10⁷ Hz
The formula between wave speed, frequency and wavelength is:
v = fλ [where v is wave speed, f is frequency and λ is wavelength]
Reorganise the equation and make λ the subject.
λ = v ÷ f
λ = (3 × 10⁸) ÷ (8.03 × 10⁷)
λ = 3.74 m [rounded to 3 significant figures]
The time must be measured with respect to gravity. As it falls, it has free fall that is the force acting on it will be the gravity.With the distance in account, d = 1/2 gt²
t = √(2d/g)
Answer:
However, scientific findings in biomedical research are not always reproducible. ... that are promoting best practices and helping researchers perform the highest-quality science. ... in life science research and actions that can be taken to improve it. ... when designing experiments, take responsibility for depicting their results ...
Explanation:
Answer:
The final speed of the train car is 8.57 m/s.
Explanation:
Given that,
Mass of train car = 1000 kg
Mass of sand = 400 kg
Speed of train car = 12 m/s
We need to calculate the final speed of the train car after the sand is dumped
Using conservation of momentum
...(I)
Put the value in the equation (I)
Hence, The final speed of the train car is 8.57 m/s.
