Answer:
Distance will be 49.34 m
Explanation:
We have given wavelength 
Diameter of the antenna d = 2.7 m
Range L = 7.8 km = 7800 m
We have to find the smallest distance hat two speedboats can be from each other and still be resolved as two separate objects D
We know that distance is given by 
So distance D will be 49.34 m
Momentum is defined as
P = m*v
where m is the mass of the object
and v is the speed of the object
We find m.............> m = P/v = 120 [kg.m/s] / 2.4 [m/s] = 50 kg
The mass is 50 kg
You're answer is B. P waves are more dynamic and have a great autonomy to be able generate a earthquake.
Answer:
its distance and displacement
Explanation:
Answer:
D. Validity group
Explanation:
A validity group is not necessarily a component of a normal experiment.
A normal experiment is made up of the dependent variables, independent variables, and most times the control group.
- The dependent variable is one that relies on the outcome of the effect produced from the experimental design
- The independent variable is the one that causes a desired effect under the study.
- The control group is a group that does not receive any treatment nor attenuation of the conditions.
