What is the relationship between the strength of an

Physics
1 answer:
Anastaziya [24]3 years ago
3 0

Answer:

As the number of turns in the coil increases, the strength  of the electromagnet increases.

Explanation:

When current flows through a coil the coil behaves as an electromagnet. The strength of electromagnet depend the amount of current, no of turns of coil and the core of coil.

B=μ₀ N I

μ₀ = permeability of the core

N = Number of turns of the coil

I = Current flowing through the coil

Increasing the current and number of coils increase the strength of electromagnet.

Which statements describe nuclear reactions? Check all that apply.
Alexandra [31]

Explanation:

Nuclear reactions are the reactions in which nucleus of an atom changes either by splitting or joining with the nucleus of another atom.

There are two types of nuclear reactions.

  • Nuclear fission - In this process, large atomic nuclei splits into smaller nuclei.  
  • Nuclear fusion - In this process, two small nuclei combine together to form a large nuclei.

Both nuclear fission and fusion processes involve nuclei of atoms.

For example, ^{0}n + ^{235}_{92}U \rightarrow ^{236}_{92}U \rightarrow ^{144}_{56}Ba + ^{89}_{36}Kr + 3n + 177 MeV

Thus, we can conclude that statements which are true are as follows.

  • Nuclear reactions involve the nuclei of atoms.  
  • The products of nuclear reactions are lighter than the reactants.

Saki is ice-staking to the left with velocity of 5 m/s. A steady breeze starts blowing. Causing saki to accelerate leftward at a
Pavlova-9 [17]

Answer:

Final velocity will be equal to 14 m/sec      

Explanation:

We have given initial velocity u = 5 m/sec

Constant acceleration is given a=1.5m/sec^2

Time t = 6 sec

We have to find the final velocity

From first equation of motion v=u+at, here v is final velocity, u is initial velocity , a is acceleration and t is time

So v=5+1.5\times 6=14m/sec

So equal final velocity will be equal to 14 m/sec

A particular solid is an excellent conductor of thermal energy. Is it more likely to be a metal or a non-metal?
tensa zangetsu [6.8K]
It is more likely to be a metal. This is because metals are good heat conductors whereas non metals tend to be poor heat conductors.

A cardinal (Richmondena cardinalis) of mass 4.20×10−2 kg and a baseball of mass 0.146 kg have the same kinetic energy. What is t
bekas [8.4K]

Explanation:

It is given that,

Mass of cardinal,m_c=4.2\times 10^{-2}\ kg

Mass of baseball, m_b=0.146\ kg

Both cardinal and baseball have same kinetic energy. We need to find the ratio of the cardinal's magnitude p_c of momentum to the magnitude p_c of the baseball's momentum.

E_c=E_b

Kinetic energy is given by, E=\dfrac{p^2}{2m}

\dfrac{p_c^2}{2m_c}=\dfrac{p_b^2}{2m_b}

(\dfrac{p_c}{p_b})^2=\dfrac{m_c}{m_b}

\dfrac{p_c}{p_b}=\sqrt{\dfrac{m_c}{m_b}}

\dfrac{p_c}{p_b}=\sqrt{\dfrac{4.2\times 10^{-2}}{0.146}}

So, \dfrac{p_c}{p_b}=\dfrac{53}{100}

So, the ratio of cardinal's magnitude of momentum to the magnitude of the baseball's momentum is 53 : 100
