Neither object will float in water. 

They both have densities greater than 1.0 g/cm³,
so both will sink to the bottom of the beaker.

Like rocks.

Answer:

None of the object float in water

Explanation:

When an object float in water than we can say that buoyancy force due to water will counter balance the weight of the object

As we can say that

W_g = F_b

so here if object is just floating or we can say that if object is in the state of sinking then we have

\rho_{object} V g = \rho_{water} Vg

so we have

\rho_{object} = \rho_{water}

so from above relation we can say that

i)\rho_{object} > \rho_{water} then it will sink inside water

ii)\rho_{object} < \rho_{water} then it will float in water

since we know density of water is 1 gm/cm^3 so here given both objects are having density more than this

so both the objects will sink inside water

Which has greater mass of a bowling ball at rest for a rolling basketball which has greater momentum
IgorLugansk [536]

Answer:

The rolling basketball has greater momentum.

Explanation:

The momentum of an object is defined as the product of mass and velocity.

Given that the bowling mass has a greater mass than the basketball,

The bowling ball is at rest, so the velocity if the ball is zero.

The basketball is rolling, it has some velocity associated with it.

Therefore, the momentum of the bowling ball is zero.

The basketball has some momentum associated with it.

Hence, the rolling basketball has greater momentum.

Why the efficiency of carnot engine is not 100%
SVEN [57.7K]

Well, actually a heat engine using the Carnot cycle whose cold reservoir is maintained at 0 K could in principle be 100% efficient, even if the hot reservoir was merely at the ambient temperature. Since it costs no energy at all to maintain a heat reservoir at the ambient temperature as long as you have a perfect thermal connection to a large thermal capacitor like your swimming pool or a nearby aquifer you’d have built a perpetual motion machine.

John, paul, and george are standing in a strawberry field. paul is 14.0 m due west of john. george is 36.0 m from paul, in a dir
sdas [7]

Position of paul with respect to john is given as

14 m due west of john

r_{pj} = r_p - r_j = -14\hat i

position of George with respect to Paul is given as 36 m in direction 37 degree south of east

r_{GP} = r_G - r_p = 36cos37\hat i - 36 sin37\hat j

now we need to find the position of George with respect to John

r_{GJ} = r_G - r_j[\tex]now for the above equation we can add the two equations[tex]r_{Gj} = -14\hat i + 36 cos37\hat i - 36sin37\hat j

r_{Gj} = 14.75\hat i - 21.67\hat j

so the magnitude is given as

r = \sqrt{14.75^2 + 21.67^2} = 26.2 m

and direction is given as

\theta = tan^{-1}\frac{21.67}{14.75}= 55.75 degree

<em>so it is 26.2 m at an angle 55.75 degree South of east</em>

The speed of a particle moving in a circle 2.0 m in radius increases at the constant rate of 4.4 m/s2. At an instant when the ma
Law Incorporation [45]

Answer:

The speed of the particle is 2.86 m/s

Explanation:

Given;

radius of the circular path, r = 2.0 m

tangential acceleration,  a_t = 4.4 m/s²

total magnitude of the acceleration, a = 6.0 m/s²

Total acceleration is the vector sum of  tangential acceleration and radial acceleration

a = \sqrt{a_c^2 + a_t^2}\\\\

where;

a_c is the radial acceleration

a = \sqrt{a_c^2 + a_t^2}\\\\a^2 = a_c^2 + a_t^2\\\\a_c^2 = a^2 -a_t^2\\\\a_c = \sqrt{a^2 -a_t^2}\\\\a_c = \sqrt{6.0^2 -4.4^2}\\\\a_c = \sqrt{16.64}\\\\a_c = 4.08 \ m/s^2

The radial acceleration relates to speed of particle in the following equations;

a_c = \frac{v^2}{r}

where;

v is the speed of the particle

v^2 = a_c r\\\\v= \sqrt{a_c r} \\\\v = \sqrt{4.08 *2}\\\\v = 2.86 \ m/s

Therefore, the speed of the particle is 2.86 m/s
