A 100 kilogram clown is fired 15 meters per second from a 500-kilogram cannon. What is the recoil speed of the cannon?

The recoil speed of the cannon is 3 m/s.

<u>Explanation:</u>

Law of conservation of momentum is used to find the recoil speed of the cannon.

m₁v₁ = -m₂v₂

m₁= mass of clown = 100 kg

v₁ = speed of the clown = 15 m/s

m₂= mass of the cannon = 500 kg

v₂ = speed of the cannon = ?

Plugin the values, we will get,

v₂ = m₁v₁ / -m₂ = -100×15/ 500 = -1500 / 500   = 3 m/s

So the recoil speed of the cannon is 3 m/s.

Phytoplankton would most likely be found _______.
DIA [1.3K]
<span>The answer is c. in the photic zone. Plankton is a diverse group of organisms that live in the water and not capable of active swimming. Phytoplankton includes a diverse autotrophic group of organisms. Since they are autotrophic, they produce their own food in the process of photosynthesis. Light is important for photosynthesis and phytoplankton tends to live in the photic zone which receives sunlight.</span>

804 n of force are applied to a 51.7 kg. What is the acceleration that the object experiences?
Andreyy89

We can use Newton II here  (where F=m*a), that F is the net (or resultant) force on the object, m is the mass of the object and a is the acceleration the object experiences.

This means, in this case there would be no friction and absolutely no other force which gives a component in the plane of motion, only then can you assume that F=804N.

Now using F= m*a

804 = 51.7*a

Therefore a = 804/51.7 = 15.55 m/s²

Which is correct about an ammeter?
s344n2d4d5 [400]

Answer:

b. The internal resistance must be much smaller than the other resistances in the circuit.

Explanation:

Ammeter is used to measure the current flowing through a circuit. It is connected in series configuration with the load. In such a scenario the resistance of the ammeter should be negligible so as to make sure that the voltage drop across the resistance of ammeter is zero and it shows the correct reading of the current in the circuit.

A large sheet of charge has a uniform charge density of 9  μCm2. What is the electric field due to this charge at a point just
Alex73 [517]

Answer:

Explanation:

Surface charge density, σ = 9 μC/m² = 9 x 10^-6 C/m²

According to the Gauss theorem,

Electric field due to the sheet is given by

E = \frac {\sigma }{2\epsilon _{0}}

E = \frac{9\times 10^{-6}}{2\times 8.854\times 10^{-12}}

E = 5.08 x 10^5 N/C

Kids are pelting a window with snowballs. On average, two snowballs of roughly 300-g mass hit the window each second, moving hor
hram777 [196]

Answer:

The average force exerted on the window due to two snowballs is 6 N

Explanation:

Given:

Mass of snowballs m = 300 \times 10^{-3} Kg

Velocity of snowball v = 10 \frac{m}{s}

For finding the average force,

Force is equal to the change in momentum,

   F = \frac{dP}{dt}

Here, final velocity is zero so we write,

 F = \frac{mv}{1}

Where dt = 1 sec

 F = 300 \times 10^{-30} \times 10

F = 3 N

Above value of force is due to one ball, but here given in question there are two ball,

F = 3 \times 2

F = 6 N

Therefore, the average force exerted on the window due to two snowballs is 6 N
