_____________________ are structures in cardiac muscle tissue that allow impulses to spread across the heart more rapidly.

Physics

Darya [45]3 years ago

Gap junctions in the intercalated discs allow impulses to be spread across the heart more quickly. This is because gap junctions allow particles/signals to pass through, thus making cells with gap junctions more able to interact.

One more thing—you posted this in the physics section rather than biology.

Why does Energy appear continuous in everyday life?
lara31 [8.8K]

Answer:

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted. Nothing happens to the energy. It does not change form, since energy has no form. ... If the energy was moving, it gets stored or re-transmitted elsewhere. Using energy means controlling its movement, rather than consuming it.

Entrepreneurship is how the person transact according to how the people negotiate. And knowledge is one of human’s invaluable efforts of giving the ideas.</span>

an object starts at rest and accelerates until it is moving at 247 km/h. if it takes 1.7minutes for this change to occur what is
d1i1m1o1n [39]

The average acceleration in 0.67 m/s^2.

The average acceleration is calculated as change in velocity/time

a=(247*5/18)/(1.7*60)

=68.61/102=0.67 m/s^2

Therefor the average acceleration of the object is 0.67 m/s^2

Find the Acceleration of a car with the mass of 1200kg and a force of 11x10^3 N
larisa86 [58]

Answer:

<h2>9.17 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{11 \times  {10}^{3} }{1200}  \\  = 9.16666...

We have the final answer as

<h3>9.17 m/s²</h3>

Hope this helps you
