4 0
The direction of the vector with respect to the x-axis
is the angle whose tangent is      (4/5) .

             Arctan(4/5) = 38.7°  counterclockwise from the x-axis.

Uma massa de 500 Kg desloca-se com velocidade 58 km por hora. Calcule o módulo de sua quantidade por movimento
Simora [160]

The momentum of the object is 8050 kg m/s

Explanation:

The momentum of an object is defined as

p=mv

where

p is the momentum

m is the mass

v is the velocity of the object

For the object in this problem, we have

m = 500 kg is its mass

v = 58 km/h is its velocity

Converting the velocity into m/s,

v=58 \frac{km}{h}\cdot \frac{1000 m/km}{3600 s/h}=16.1 m/s

Therefore now we can find the momentum of the object:

p=(500)(16.1)=8050 kg m/s

What in th max age of a dog
Anna11 [10]
Ok, SO my family runs a Dog Day Care. ( littlecanineclubhouse.com if you need proof.)

And what i have found it that it really depends on the type of dog it is.

Such as a PUG, they can live anywhere between 15 to 20 years.
A Boston Bull Terrier can live up to about 10 to 15 years.
A French Bull dog can live anywhere up to 10 to 12 years.
A golden Retriever can live up to 10 to 12 years. 
ETC. 

SO it really depends on the dog.

What are similarities between the Rorschach inkblots and the TAT test?
Luden [163]
The Rorschach inkblots and the TAT (Thematic Appreciation Test) both rely on providing the subject with ambiguous visual stimuli and assessing the subject's state of mind using the subject's interpretation of the stimuli.
Both use cards, although not all of the cards are used in the TAT. Moreover, the TAT cards contain sketches, while the Rorschach inkblots contain patterns of ink.

Suppose that you can throw a projectile at a large enough v0 so that it can hit a target a distance R downrange. Given that you
NikAS [45]

Answer:

Theta1 = 12° and theta2 = 168°

The solution procedure can be found in the attachment below.

Explanation:

The Range is the horizontal distance traveled by a projectile. This diatance is given mathematically by Vo cos(theta) t. Where t is the total time of flight of the projectile in air. It is the time taken for the projectile to go from starting point to finish point. This solution assumes the projectile finishes uts motion on the same horizontal level as the starting point and as a result the vertical displacement is zero (no change in height).

In the solution as can be found below, the expression to calculate the range for any launch angle theta was first derived and then the required angles calculated from the equation by substituting the values of the the given quantities.
