Answer:
Emperor penguins are near the top of the Southern Ocean’s food chain. They have a varied menu that changes with the season. Some prey items are more important than others. One of the most frequently eaten prey species is the Antarctic silverfish Pleuragramma antarcticum. They also eat other fish, Antarctic krill and some species of squid. Most prey items are small. Since they are very cold when ingested, their small size makes it easier to bring food up to body temperature to digest it.
what are the effects of atmospheric pressure
Answer:
Cloudiness, Wind, and Precipitation. There's more effects produced because of force is more if the surface of the area is smaller, and less when the surface is larger. It also affects weather, it can be measured with a barometer.
Explanation:
the total resistance of the circuit
The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω
Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.
Answer: 3
Explanation: If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

Mr Mann cut a cucumber. Mr Mann said, you have performed a chemical change. Is he right?
Answer:
No.
Explanation:
The cut cucumber is still a cucumber.
Answer:
Nope.
Explanation:
Chemical change is transforming the cucumber into a pickle. However, you need vinegar, so it isn't a full change.
Therefore, Mr. Mann would not be right either way, because all he did was cut a cucumber, and he should probably get some help with all this "chemical change".

A wire carries a current of 6.52 A in a direction that makes an angle of 44.8 degrees with the direction of a magnetic field of strength 0.258 T. What is the magnetic force on a 3.61 m length of wire
Answer:
[tex]F=4.27N[/tex]
Explanation:
From the question we are told that:
Current [tex]I = 6.52 A[/tex]
Angle [tex]\theta= 44.8 \textdegree[/tex]
Magnetic field [tex]B= 0.258 T.[/tex]
Length [tex]l=3.61m[/tex]
Generally the equation for Magnetic force F is mathematically given by
[tex]F=BIlsin\theta[/tex]
Therefore
[tex]F=0.258*6.52*3.61*sin 44.8[/tex]
[tex]F=4.27N[/tex]

Which of the following are not vectors?
Answer:

What is the average velocity of the object from t=1s to t= 3 s?
A. 1 m/s
B. 0.5 m/s
C. -0.5 m/s
D. -1 m/s
Answer:
Explanation:
Since this is a distance v time graph, the slope of the line from 1s to 3s is the velocity. However, it looks like, at t=3, the velocity is 0, so getting the definite velocity is not going to happen. We can estimate it as closely as possible. Since the line is tending from the upper left to the lower right, the slope is negative, so the velocity is also negative. That leaves only C or D as our answers. And the slope is closer to -1 than to -5, so choice D. is the one you want.

Calculate the amount of force required to produce motion in a car of 1000kg with an acceleration of 5m/s square.
Answer:
5000 N
Explanation:
F=ma
=1000*5
=5000N
Here's the solution,
mass = 1000 kgacceleration = 5 m/s²now, we know
[tex] \large \boxed{f = m \times a}[/tex]
so,
[tex] \hookrightarrow \: f = 1000 \times 5[/tex][tex] \hookrightarrow \: f = 5000[/tex]The force required is 5000 Newtons.

A pitcher claims he can throw a 0.174 kg baseball with as much momentum as a speeding bullet. Assume that a 5 g bullet moves at a speed of 1,115 m/s. What must the baseball’s speed (m/s) be if the pitcher’s claim is valid?
Answer:
[tex]320.4\:\mathrm{m/s}[/tex]
Explanation:
The momentum of an object is given by [tex]p=mv[/tex]. Therefore, we have the following equation:
[tex]m_{ba}v_{ba}=m_{bu}v_{bu},\\0.174\cdot v_{ba}=0.005\cdot 1115,\\v_{ba}\approx \boxed{320.4\:\mathrm{m/s}}[/tex]
