10. What are the units for distance,

Physics
1 answer:
Rashid [163]4 years ago
3 0

Answer:

C.

Explanation:

Distance is meters its shortcut is (m). This is because it measures how long/far something is. Velocity is m/s (or meters per second). This is because velocity and speed are pretty much the same but, velocity is speed with direction. Also, time of course is seconds because that is a common unit of time.

A force of 350 N causes a body to move with an acceleration of 10 m/s2. What's the mass of the body?
uysha [10]
Answer is: <span>the mass of the body is 35 kg.
</span>Newton's second law of motion: F = m · a.
F - <span> force applied.
m - </span><span>mass of the object receiving the force.
</span>a<span> - the acceleration of the object.
</span>F = 350 N.
a = 10 m/s².
m = ?
m = F ÷ a.
m = 350 N ÷ 10 m/s².
m = 35 kg.
<span>One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in direction of the applied force.</span>

A kettle transfers 6,000j of energy electrically. 1,500j of this is wasted. what is the efficiency of this kettle?
Mashcka [7]

Answer:75 percent

Explanation:so in order tro fin d thge efficiency i used the forumla ,efficency=useful output energy/input energyx100%,in order to use this formula i needed the output,which i found by subtracting the input energy with wasted energy,that gave me the output,and after founding the output,i put that into the formula,

output energy=input energy - wasted energy

output energy=6000j-1500j

output energy=4500

put that into the formula

efficiency =output energy/input enrgy x100%

efficiency=4500/6000 multiplied by 100%

efficiency=0.75x100%

efficiency=75%

During a breath, the average human lung expands by about 0.50 l. part a if this expansion occurs against an external pressure of
saveliy_v [14]
Work, in thermodynamics, is the amount of energy that is transferred from one system to another system without transfer of entropy. It is equal to the external pressure multiplied by the change in volume of the system. It is expressed as follows:<span>

W = PdV

Integrating and assuming that P is not affected by changes in V or it is constant, then we will have:

W = P (V2 - V1)

Substituting the given values:
P = 1.0 atm = 101325 Pa
(V2 - V1) = 0.50 L = 
W = 101325 N/m^3 ( 0.50) (1/1000) m^3
W = 50.66 N-m or 50.66 J
<span>
So, in the expansion process about 50.66 J of work is being done.
