Two Forces Of Magnitude 20N Each Are Acting At 30 And 60 degree with xAxis the Y Component Of The Resultant Force Is

Physics

vodka [1.7K]3 years ago
5 0

We can find the y-component of the resultant force by adding the y-components of the two 20N forces.

For a force of magnitude F and lying at an angle off the x-axis θ, the y-component of the force is given by:

Fsin(θ)

The magnitude of the two forces is 20N, and they lie at 30° and 60°, so the sum of their y-components, and therefore the y-component of the resultant force, is:

20sin(30°)+20sin(60°)

= 27.3N

In the equation 234Th90 -> 234Pa91 + X, which particle is represented by X?
taurus [48]
This process shows alpha decay so X represents an alpha particle. The characteristic of alpha decay is that the mass number stays constant while the proton number increases.

You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizont
Scilla [17]

Answer:

R_{max} = 51.84 m

Explanation:

When we shoot the dart upwards the time taken by the dart to go straight up and again come back is given as

t = 4.6 s

here we can say

\Delta y = 0 = v_i t + \frac{1}{2}at^2

0 = v_i t - \frac{1}{2}(9.8)t^2

put t = 4.6 s then we have

v_i = 22.54 s

Now in order to find the maximum range we can say

R = \frac{v^2 sin2\theta}{g}

so in order to have maximum range we can say

\theta = 45 degree

R_{max} = \frac{v^2}{g}

R_{max} = \frac{22.54^2}{9.8}

R_{max} = 51.84 m
