Answers
Answer:
The weight of an object is the force it exerts due to gravity. Pressure is force per unit area, or force divided by area over which the pressure is exerted.
Explanation:
1. For Jo:
1. For Jo:force = 500 N
1. For Jo:force = 500 Narea = 0.0001 m^2
1. For Jo:force = 500 Narea = 0.0001 m^2pressure = F/A = 500N/0.0001m^2 = 5,000,000 N/m^2

find the current and voltage across each resistor in the given circuit.
Answers
Answer:
R1, R4: 1.3433 VR2: 0 VR3: 6.3134 VExplanation:
The resistor R2 is shorted out, so is not in the circuit. The remaining resistors are in a series circuit with a total resistance of ...
R1 +R3 +R4 = 1k +4.7k +1k = 6.7k
The current is the ratio of the applied voltage to this total resistance:
I = V/R = (9 v)/(6.7k) ≈ 1.3433 mA
The voltage across each resistor is the product of this current value and the resistance:
R1 voltage = (1 kΩ)(1.3433 mA) = 1.3433 volts
R2 voltage = 0
R3 voltage = (4.7 kΩ)(1.3433 mA) = 6.3134 volts
R4 voltage = (1 kΩ)(1.3433 mA) = 1.3433 volts
What is the major difference between metallic bonding and ionic bonding?
Answers
Answer:
The key difference between ionic bonding and metallic bonding is that the ionic bonding takes place between positive and negative ions whereas the metallic bonding takes place between positive ions and electrons.
Explanation:
About (metallic bonding) → Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions.
About (ionic bonding) → Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds

Book A with a mass of 1.00 kg is placed on a horizontal table. Book B with a mass of 0.500 kg is placed on top of book A. What is the magnitude of the normal force exerted on book A by the table?
Answers
Answer:
Explanation:
N = mg = (1.00 + 0.500)(9.81) = 14.7 N
The magnitude of the normal force exerted on book A by the table is 14.7 N
ForcesFrom the question, we are to determine the magnitude of the normal force.
The normal force ca be calculated by using the formula
[tex]F_{n} = mg[/tex]
Where [tex]F_{n}[/tex] is the normal force
m is the mass
and g is the gravitational field strength ( g = 9.8 m/s²)
The mass will be addition of the masses since Book B is placed on top of the book.
Thus,
m = 1.00 kg + 0.500 kg = 1.50 kg
Then,
[tex]F_{n} = 1.5 \times 9.8[/tex]
[tex]F_{n} = 14.7 \ N[/tex]
Hence, the magnitude of the normal force exerted on book A by the table is 14.7 N

By the time children are five years old:
A. the typical 90-minute sleep cycles of alternating REM and NREM are established.
B. about 50 percent of sleep time is spent in REM sleep and 50 percent is spent in quiet sleep that is very similar to NREM stages 1 and 2.
C. their sleep pattern is characterized by 60-minute sleep cycles, producing up to 13 cycles per day.
D. they will begin to experience their first dreams and nightmares.
Answers
Option D is correct. Around the age of five, children begin to experience their first dreams and nightmares
By the time children are five years old, several developments occur in their sleep patterns.
Option A is incorrect because the typical 90-minute sleep cycles of alternating REM (Rapid Eye Movement) and NREM (Non-Rapid Eye Movement) are not yet established at this age.
Option B is also incorrect as the sleep time distribution between REM sleep and quiet sleep (similar to NREM stages 1 and 2) is not necessarily equal at this stage.
Option C is inaccurate because 60-minute sleep cycles producing up to 13 cycles per day do not align with the typical sleep patterns of five-year-olds.
However, option D is correct. Around the age of five, children begin to experience their first dreams and nightmares.
This is an important milestone in their cognitive and emotional development, as it reflects the maturation of the brain regions involved in dreaming and the processing of emotions during sleep.

The displacement of your motion during the entire motion is 22.5 m
The given parameters;
your initial velocity, u = 1.5 m/syour final velocity , v = 3 m/stime of motion, t = 10 sThe displacement of your motion during the entire motion is calculated from your average velocity and time of motion.
This magnitude of this displacement is calculated as follows;

A jet airplane is in level flight. The mass of the airplane is m = 8930 kg. The airplane travels at a constant speed around a
circular path of radius R = 8.01 mi and makes one revolution every T = 0.106 h. Given that the lift force acts perpendicularly
upward from the plane defined by the wings, what is the magnitude of the lift force acting on the airplane?
At what angle is the airplane banked?
Answers
Answer:
Explanation:
The lift force will have a vertical component equal to the weight of the plane and a horizontal component sufficient to supply the needed centripetal accleration.
R = 8.01 mi = 12891 m
ω = 2π/T = 2π/(0.106(3600)) = 0.016465 rad/s
F = m√(g² + (ω²R)²)
F = 8930√(9.81² + (0.016465²(12891))²)
F = 8930√(9.81² + 3.49²)
F = 92,996.480...
F = 93.0 kN
θ = arctan(3.49/9.81) = 19.6°
