How fast a typical 2.0 mg mosquito would have to fly (in mm/s) to have an amount of energy delivered to the eardrum each second when someone whispers (20 dB) a secret in your ear?
-</span><span>3.5 joules</span>
The solid cylinder reaches the bottom first.
A solid object will always roll down the ramp faster than a hollow object of the same shape regardless of their exact mass or diameter.
The solid cylinder has a lower moment of inertia than the hollow one does. Although they have the same mass, all the hollow cylinder's mass is concentrated around its outer edge so its moment of inertia is higher.
The velocity would be greater for the material with radius of gyration k is lower of for which the moment of inertia is lower. Solid cylinder with k as 1/2 will have greater velocity as compared to hollow cylinder which has k as 1. As they have same mass and radius their energies at both the levels would remains same including the potential energy and energy lost due to friction.

Answer:
volume of substance of weight of mercury is 13593 kilograms
Answer:
Explanation:
Given that,
The elevator is moving up and slowing down at the rate of, 
The acceleration due to gravity, 
Mass of the person, m = 93.3 kg
To find,
The reading of the scale.
Solution,
As the elevator is moving down with some acceleration. The net force acting on it is given by :
So, the scale will read 1194.24 N.
A subcritical state will result by flattening a critical mass of fissionable material into the shape of a hamburger.
To find the answer, we need to know about the critical mass.
<h3>What is critical mass?</h3>
- A material's nuclear characteristics (particularly, its nuclear fission cross-section), density, shape, enrichment, purity, temperature, and environment all affect its critical mass.
- A mass of fissile material is considered to be in a critical state when a nuclear chain reaction in the mass is self-sustaining and there is no change in power, temperature, or neutron population.
- At a specific temperature, a mass might be precisely critical.
- A subcritical state will result by flattening a critical mass of fissionable material into the shape of a hamburger.
- The cross sections for fission and absorption grow as the relative neutron velocity drops.
Thus, we can conclude that, a subcritical state will result by flattening a critical mass of fissionable material into the shape of a hamburger.
