So we want to know what measurement do we need to make in order to determine what equipment can the boat carry. The boat overall length dictates what equipment should a boat have to comply with federal and state law. So the correct answer is the LENGTH measurement.
Answer:
a)
b)
Explanation:
Apparent frequency of the siren is given as
as we know that the wavelength will remain the same as it is having originally
sowe know
a) Now when wind is blowing from source to official
so we have
so we have
b) Now when wind is from official to source
so we have
so we have
going to the toilet, and keeping cleant. no nasty bits floating around but they are weightless !
eating. pushing a fork would push back by newton 3. can't brace themselves to cut
Answer:
Wavelength
Explanation:
Wavelength is the distance between successive trough or crest of a wave
Answer:
D. 48.985 N
Explanation:
Newton's second law states that:
which means that the net force acting on an object is equal to the product between the object's mass and its acceleration.
The equation of the forces for the briefcase in the elevator therefore is given by:
where
N is the normal reaction exerted on the briefcase
(mg) is the weight of the briefcase, with
m = 4.5 kg being its mass
g = 9.8 m/s^2 is the acceleration of gravity
a = 1.10 m/s^2 is the acceleration
Here we chose upward as positive direction.
Solving for N, we find the normal force:
So the closest answer is
D. 48.985 N
