Answer:
The acceleration of the sliding toboggan is, a = 4.9 m/s²
Explanation:
Given data,
The total weight of the toboggan, W = 1300 N
The slope is, Ф = 30°
The acceleration of a body under the influence of the gravitational field does not depend on its mass, size and shape in the absence of the air resistance.
Therefore,
The acceleration of the toboggan is given by the formula,
a = g Sin Ф
Substituting the given values in the above equation,
a = 9.8 x Sin 30°
= 4.9 m/s²
Hence, the acceleration of the sliding toboggan is, a = 4.9 m/s²
Answer:
Explanation:
kinetic energy=1/2*mass*velocity^2
=1/2*14kg*10^2
=7*100
=700 joule
Answer:
The new time period is
Explanation:
From the question we are told that
The period of oscillation is
The new length is
Let assume the original length was
Generally the time period is mathematically represented as
Now I is the moment of inertia of the stick which is mathematically represented as
So
Looking at the above equation we see that
=>
=>
=>
Answer:
d
Explanation:
there is not enough information about the liquid to know the force required for each. ie. stirring a cup of water is different than stirring a cup of pudding.
The best and most correct answer among the choices provided by your question is the second choice or letter b.
Ex is negative from x = -2 to x = 0, and positive from x = 0 to x = 2 <span>correctly describes the orientation of the x-component of the electric field along the x-axis.</span>
