Answer:
The horizontal component of this force is about 36 N.
Explanation:
Given that,
Bruce is is pulling on his lead with a force of 40 N
Angle below horizontal,
We need to find the horizontal component of this force. The horizontal component of any vector is given by :
or
So, the horizontal component of this force is about 36 N. Hence, this is the required solution.
Running the lid of a tight-fitting jar under hot water causes it to expand due to thermal expansion, which makes it easier to remove from the jar.
When the lid of a tight-fitting jar is run under hot water, it undergoes thermal expansion due to the increase in temperature. The expansion of the lid causes it to slightly loosen, making it easier to remove from the jar. This happens because metals have higher coefficients of expansion than glass, so the lid expands more than the jar itself.

The birds can glide in the air without moving their wings by maintaining the thrust of the air by their weight and move downward at a very slower rate.
Further Explanation:
The birds have a capability of flying high in the air without flapping their wings and still not falling down rather they glide downwards due to the up thrust of the air. This technique of the birds to keep them in the air without flapping their wings is termed as soaring.
The soaring birds make use of the air current and its thrust on their primary wings so that there is no turbulence experienced by them due to the pointed tips of their primary wings.
The birds should possess some mass in order to maintain a balance between the thrust and the weight of their body. That’s why the small birds are not able to maintain their flight but the bigger birds like vulture, eagle etc. experience sufficient air drag in order tio maintain their flight.
Thus, the birds can glide in the air without moving their wings by maintaining the thrust of the air by their weight and move downward at a very slower rate.

B.) The gravitational force is balanced out by the force of friction.
C.) The gravitational force between them is extremely small.
D.) The gravitational attraction is balanced by an equal and opposite gravitational repulsion
Answer:
C.) The gravitational force is balanced out by the force of friction.
Answer:
C. The gravitational force between them is extremely small.
Explanation:
The force of gravity is based off of the mass and distance of two objects. Stephen and Andy don't have large enough masses to feel an effect.
