Answer:

d=5\ g/cm^3

Explanation:

Given that,

Mass of the object, m = 100 grams

Volume of the object, V = 20 cm³

We need to find the density of the object. We know that, density is equal to mass per unit volume. So,

d=\dfrac{m}{V}\\\\d=\dfrac{100\ g}{20\ cm^3}\\\\d=5\ g/cm^3

So, the density of the object is equal to 5\ g/cm^3.

A rock is thrown upward from level ground in such a way that the maximumheight of its flight is equal to its horizontal rangeR.
Snowcat [4.5K]
A) The vertical component of velocity v is taking the rock to a height

Vertical component = vsin\theta
The time taken to reach maximum height = \frac{vsin\theta}{g}
So total time of rocks flight = \frac{2vsin\theta}{g}
Range of rock is due to the horizontal component of velocity = vcos\theta
Range = \frac{2*v*sin\theta*v*cos\theta}{g} = \frac{2*v^2*sin\theta*cos\theta}{g}
Maximum height = \frac{g*t^2}{2} = \frac{v^2*sin^2\theta}{2*g}
Since range = maximum height
We have \frac{2*v^2sin\theta*cos\theta}{g} = \frac{v^2*sin^2\theta}{2*g}
tan\theta = 4
\theta = 75.96^0
So when angle of projection is \theta = 75.96^0 range is equal to maximum height reached.
b) We have range = \frac{2*v^2*sin\theta*cos\theta}{g} =\frac{2*v^2*sin2\theta}{g}
Maximum of range is reached when \theta = 45^0
Maximum range = \frac{2*v^2}{g}
c) For range to be equal to maximum height only condition is tan\theta = 4, it does not depend upon acceleration due to gravity and velocity. That angle is a constant.

A piano is hanging by a rope. Beside it are two vectors. The vector pointing upward is longer and labeled F Subscript T Baseline
RideAnS [48]

The net force acting on the piano is 500N

<h3>When is two vectors Parallel ?</h3>

There will be parallel vectors when two vectors are moving in the same direction or opposite direction.

Given that a piano is hanging by a rope. Beside it are two vectors. The vector pointing upward is longer and labeled F_{T} = 6,000 N. The second vector is downward and labeled F_{g} = 5,500 N which will be negative because it will be acting downward.

Let the net force be F_{N}. Then,

F_{N} = F_{T} + F_{g}

F_{N} = 6000 - 5500

F_{N} = 500 N

Therefore, the net force acting on the piano is 500N

The velocity of a 150 kg cart changes from 6.0 m/s to 14.0 m/s. What is the magnitude of the impulse that acted on it?
aleksandrvk [35]
M = 150 kg.

Final velocity, v = 14 m/s

Initial Velocity, u = 6 m/s

Impulse =  m(v - u)
 
             = 150*(14 - 6)
           
             =  150*8 = 1200 kgm/s  or 1200 Ns
