A bullet is fired straight up from a gun with
a muzzle velocity of 166 m/s.
Neglecting air resistance, what will be its
displacement after 8.6 s? The acceleration of
gravity is 9.8 m/s
Answer in units of m.
Explanation:
u=166m/s, v=0(at it's highest point final velocity is zero), a=9.8m/s², t=8.6s
by the formula, S=ut+½at².
S=[166×8.6+½.×9.8×(8.6)²]. ...by calculation
S = 1427.6+362.404
S=1790.004m

Can I please get help with this?
can you predict a dark room is empty or not with the help of sound? how?
please help me ।
50 points
Answer:
Sound waves can reflect off surfaces. We hear sound reflections as echoes. Hard, smooth surfaces are particularly good at reflecting sound. This is why empty rooms produce lots of echoes.
Soft, rough surfaces are good at absorbing sound. This is why rooms with carpets and curtains do not usually produce lots of echoes.
Explanation:
With this information, you'd be able to come up with your answer,

What does a higher value of k and a lower value of k tell about the strength of the spring? (Hint: In which case is it soft or stiff?)
Answer:
' In layman's terms, the k variable in Hooke's law (F = -kx) indicates stiffness and strength. The higher the value of k, the more force is needed to stretch an object to a given length. This value is dependent on the object's material alongside its shape and Proportons

What acceleration would you expect a 100 kg individual to experience from a 1000N force?
Answer: 10 m/2^2
F=ma
Explanation:
Force = 1000N
1 N is 1 (kg*m/s^2)
Mass = 100kg
F=ma
a = F/m
a = (1000kg*m/s^20/(100kg)
a = 10 m/s^2

what supports a white dwarf against the crush of gravity?
Answer: In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.
Explanation:
Degeneracy pressure keeps a white dwarf from collapsing under its own gravity.
What is Degeneracy pressure?Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.
The maximum mass that a white dwarf can support against collapse is 1.4 solar masses due to the Chandrasekhar limit.

1. If there are two objects of equal size but object A is heavier than object B, which statement is TRUE according to Newton’s second law of physics?
A.
Object A will require less force to be set in motion and will travel faster.
B.
Object B will require less force to be set in motion and will travel faster.
C.
Object A will require more force to be set in motion but will travel faster than object B.
D.
Object B will require more force to be set in motion but will travel faster than object A.
2. For athletes, a focus on body mechanics improves the effectiveness of their efforts.
A.
True
B.
False
The answers are 1. According to Newton's second law, object A, being heavier, requires more force to be set in motion and will travel faster than object B. The correct answer is options C. and 2. Focusing on body mechanics is important for athletes as it improves their effectiveness, and technique, and reduces the risk of injury is a true statement.
1. According to Newton’s second law of physics, if there are two objects of equal size but object A is heavier than object B, then the statement that is true is option C: Object A will require more force to be set in motion but will travel faster than object B. Newton's second law of motion states that acceleration is directly proportional to the force applied and inversely proportional to the object's mass. Since both objects are of equal size but object A is heavier, it will require more force to be set in motion. However, once in motion, it will have more inertia and travel faster than object B.2. The statement "For athletes, a focus on body mechanics improves the effectiveness of their efforts" is True. Body mechanics refers to the way in which the body moves and maintains balance while performing a physical task. Athletes need to have proper body mechanics to achieve maximum efficiency and reduce the risk of injury. By focusing on their body mechanics, athletes can improve their technique, reduce unnecessary movements, and improve their overall performance. Good body mechanics can also help to prevent injury and reduce wear and tear on the body. Therefore, a focus on body mechanics is essential for athletes to maximize their performance while minimizing their risk of injury. In summary, Newton's second law states that a heavier object requires more force to be set in motion, while a focus on body mechanics can improve the effectiveness of athletes' efforts.For more questions on Newton's second law
