I need a picture please befor i can answer
Its structure.
The function of the enzymes are determined by their structure.
The first problem cannot be solve because you did give the distance or length of the rope, because work = distance x force. i can only solve the the second problem. since the bucket is moving up then force due to gravity is going down, then the net force is:
Fnet = F1 - Fg
where Fg = mg
g is the accelaration due to gravity ( 9.81 m/s^2)
Fnet = 57.5 N - (3.9 kg)(9.81) N
Fnet = 19.24 N
Answer:
<h2>1 volt and 0.5 volt</h2>
Explanation:
Given data
voltage supplied Vs= 1.5 volts
resistance R1= 1000 ohms
resistance R2= 500 ohms
The total resistance is
Rt= 1000+ 500
Rt= 1500 ohms
The current I is given as

Voltage across R1

Voltage across R2

In series connection the current is the same for all components while the voltage divides across all components,the voltages consumed by each individual resistance is equal to the source voltage.
<span>Time needed for drive a distance 100 km at 100 km/h:
t1 =100/100
= 1 h
Time needed for drive a distance 40 km at 45 km/h:
t2 =40/45
=0.8 h
t3 =3h 15m - 1 h- 0.8 h
=1.45 h
Distance to town equals:
s3 =270-100-40
=130 km
Least speed needed to arrive in time for the interview:
v3 =130 km/1.45 h
=89.65 km/h
The answer is 89.65 km/h</span>
