Using a scale of 1 cm to represent 10 N, find the size and direction of the resultant of forces of 50 N

Physics

Answer:

74.31\ \text{N}

16.59^{\circ}

Explanation:

P = 50 N

Q = 30 N

\theta = Angle between the vectors = 45^{\circ}

Resultant is given by

R=\sqrt{P^2+Q^2+2PQ\cos\theta}\\\Rightarrow R=\sqrt{50^2+30^2+2\times 50\times 30\times \cos45^{\circ}}\\\Rightarrow R=74.31\ \text{N}

Angle of resultant

\phi=\tan^{-1}\dfrac{Q\sin\theta}{P+Q\cos\theta}\\\Rightarrow \phi=\tan^{-1}\dfrac{30\times \sin45^{\circ}}{50+30\cos45^{\circ}}\\\Rightarrow \phi=16.59^{\circ}

Magnitude of the resultant is 74.31\ \text{N}

Direction of the resultant is 16.59^{\circ}

klio [65]

Answer:

A. 40N

B. 5m/s

Explanation:

A.

Impulse is equal to the area under the curve of a force vs. time graph. In this case, the area is in the shape of a triangle with base 8 (12-4=8) and perpendicular height 10:

<em>Area of a triangle = (1/2)bh</em>

A=(1/2)*8*10

=40

ANSWER: 40N

B.

<em>Impulse = mass * velocity</em>

40 = 8v

v = 5

ANSWER: 5m/s

CAN ANYONE GIVE ME SOME INFO ON THE THERMOSPHERE
Pachacha [2.7K]
The thermosphere is the layer of the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions in the ionosphere.
