1.What is the kinetic energy of a 394kg car moving at 15 m/s?

Physics
1 answer:
-BARSIC- [3]3 years ago
6 0

FORMULA:

  • K.E. = 1/2mv²

ANSWER:

We are given with mass of truck 95kg and K.E. truck 150,000J.

Plugging the respective value, by assuming velocity = v:

  • 150,000 = 1/2 × 95 × v²
  • 150,000 × 2/95 = v²
  • 3157.89 = v²
  • √3157.89 = v
  • 56.19m/s = v

Whose series of experiments identified the nucleus of the atom?
Wewaii [24]

Answer:

Rutherford

Explanation:

In 1911, E. Rutherford and his collaborators bombarded a thin gold foil with alpha (positive) particles, coming from a radioactive material, at high speed. The experiment allowed observing the following behavior in the released particles: Most of them passed through the sheet without changing direction, as expected. Some deviated considerably e. A few particles bounced towards the emission source.

In the Rutherford Model the positive charge is concentrated in a central nucleus, so that the positive particles that pass very close to it, deviate enough from their initial trajectory and only those few that collide directly with the nucleus return in the direction of which they come from .

The Rutherford Model states that: The atom has a central zone or nucleus where the total positive charge (that of the protons) and most of the mass of the atom, provided by the protons and neutrons. It also has an outer zone or cortex where electrons are found, which revolve around the nucleus. (Actually, the nucleus particles (protons and neutrons) were discovered after Rutherford established his model. Rutherford's experiment only reported a small, positive nucleus, did not clarify anything else) .

Intensity: Radiation of a single frequency reaches the upper atmosphere of the earth with an intensity of 1350 W/m2. What is the
sesenic [268]

Answer:

The right answer is "1010 V/m".

Explanation:

The given values are:

Intensity,

I=1350 \ W/m^2

c = 3.00\times 108 \ m/s

\mu_0= 4\pi\times 10^{-7} \ T.m/A

Now,

The electric field's maximum value will be:

=  \sqrt{2\times u\times c\times I}

On substituting the values in the above formula, we get

=  \sqrt{2\times 4\times \pi\times 10^{-7}\times 3\times 10^8\times 1350}

=  \sqrt{32400\times 3.14\times 10^{-7}\times 10^8}

=  1010 \ V/m

likoan [24]

Answer:

The answer is False.

Explanation: The FDA (food and drug administration) is a regulatory agency of the United state Government, they regulate the production and distribution of food and drugs within the United States of America, ensuring that standards are met and followed.

Most of the approvals given to food and drugs by FDA are done based on random sampling of products which may not be able to capture all the defective products in a given lot or batch of supplies, which is why it very necessary to take other measures to verify the wholesomeness, authenticity etc of a given product before purchasing or making use of such products.
