Think about what subsequently happens to the ketchup, which is initially at rest, and use newton's first law to explain why this
Vika [28.1K]

Newton's first law of ketchup is  if the bottle of ketchup is smacked upward, the contents (the ketchup) will tend to remain in place, and it will be closer to the opening in the bottle.

<h3>Further explanation </h3>

If we are trying to get ketchup out of the bottle, the best way to do it is to turn the bottle upside down and give the bottle a upward smack which force the bottle rapidly upward.

Newton first law said that every object tries to continue in its state of rest or uniform motion unless an external force acted upon it (In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force).   Newton first law describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.

Inertia explained by Sir Isaac Newton in his first law of motion (Newton law of motion). The law states that an object at rest stays at rest and an object continues its state of motion until an external force acts on it. The examples are one's body movement to the side when a car makes a sharp turn

Two coils that are separated by a distance equal to their radius and that carry equal currents such that their axial fields add
jok3333 [9.3K]

Answer:

When x = 2.8 cm, B_{x1} = 0.0265 T

When x = 5.5 cm, B_{x2} = 0.0209 T

when x = 7.3 cm, B_{x3} = 0.0169 T

When x = 11.0 cm, B_{x4} = 0.0103 T

Explanation:

According to Biot-Savart law,

B_{x} = \frac{N \mu_{o}IR^{2}  }{2(x^{2} +R^{2}  )^{3/2} }\\.......................(1)

R = 11.0 cm = 0.11 m

I = 17.0 A

N = 300 turns

\mu_{o}  = 4\pi  * 10^{-7} N/A^{2}

When x₁ = 2.8 cm = 0.028 m

B_{x1} = \frac{300 *(4\pi * 10^{-7} ) *  17 *0.11^{2}  }{2(0.028^{2} +0.11^{2}  )^{3/2} }\\B_{x1} = 0.0265 T

When x₂ = 5.5cm = 0.055 m

B_{x2} = \frac{300 *(4\pi * 10^{-7} ) *  17 *0.11^{2}  }{2(0.055^{2} +0.11^{2}  )^{3/2} }\\B_{x2} = 0.0209 T

When x₃ = 7.3 cm = 0.073 m

B_{x3} = \frac{300 *(4\pi * 10^{-7} ) *  17 *0.11^{2}  }{2(0.073^{2} +0.11^{2}  )^{3/2} }\\B_{x3} = 0.0169 T

When X₄ = 11.0 cm = 0.11 m

B_{x4} = \frac{300 *(4\pi * 10^{-7} ) *  17 *0.11^{2}  }{2(0.11^{2} +0.11^{2}  )^{3/2} }\\B_{x4} = 0.0103 T

What type of motor operates at a constant steady-state speed regardless of the load?
LekaFEV [45]
The type of motor that allows for constant speed regardless of load are called Geared Speed Control motors. This type of motor has a tachometer feedback device attached at the rear of the motor that gives constant feedback to the speed controller giving the advantage of constant speed regardless of load. The tachometer allows for varied frequency delivery to the motor to maintain pre-set output speed.

A 80 kg parent and a 20 kg child meet at the center of an ice rink. They place their hands together and push. The parent pushes
Ymorist [56]

Answer:

force acting on the parent = 25 N .

Explanation:

According to third law of Newton , there is equal and opposite reaction to every action . Here force by the parent on child is action and the force by child on parent is reaction . The former is given as 25 N so force by child on parent will also be 25 N .

Answer is 25 N .
