Magnetic fields are areas where an object exhibits a magnetic influence. The fields affect neighboring objects along things called magnetic field lines. A magnetic object can attract or push away another magnetic object. You also need to remember that magnetic forces are NOT related to gravity. The amount of gravity is based on an object's mass, while magnetic strength is based on the material that the object is made of.
This distance is known as the amplitude of the wave, and is the characteristic height of the wave, above or below the equilibrium position. Normally the symbol A is used to represent the amplitude of a wave. The SI unit of amplitude is the metre (m).
<h2>
Time taken is 0.459 seconds</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 0 m/s
Final velocity, v = 81 km/hr = 22.5 m/s
Time, t = ?
Acceleration, a = 49 m/s²
Substituting
v = u + at
22.5 = 0 + 49 x t
t = 0.459 seconds
Time taken is 0.459 seconds
The strength of the friction doesn't matter. Neither does the distance or the time the asteroid takes to stop. All that matters is that the asteroid has
1/2 (mass) (speed squared)
of kinetic energy when it lands, and zero when it stops.
So
1/2 (mass) (original speed squared)
is the energy it loses to friction in order to come to rest.
Answer:
The biggest advantage of Solar cookers is their eco-friendliness. By exploitation one you’ll decrease your dependence on gas or electricity, cut back your carbon footprint, and save on fuel and therefore the value of fuel on running home appliances. change of state with star cookers clearly needs daylight, that makes it troublesome to use throughout winter months and on rainy days. change of state conjointly takes a considerably longer time compared to traditional strategies. Users should schedule their change of state time and maximize the employment of daylight. As a result, preparation should begin early within the morning in order that the food may be placed in the cooking utensil by noontide.
