Answer:

hey from what I know the answer is C

Explanation:

When a book is kept on a table , weight (gravitational force) of book acts on table vertically downwards and as a reaction of weight , table also exerts an equal and opposite ( upward) force on book .

Nicolo` works on weekends at a Slow Food Parlor. He fills a pitcher full of Cola, places it on the counter top and gives the 2.6

Slav-nsk [51]

Answer:4.22 J

Explanation:

Given

mass of pitcher $m=2.6\ kg$

Force applied $F=8.8\ N$

distance moved $s=48\ cm$

Applying work-Energy theorem which states that work done by all the forces is equal to the change in kinetic energy of the object

Work done by force $W=F\cdot s$

W= $8.8\times 0.48 J$

change in kinetic Energy = $\frac{1}{2}mv^2-0$

$8.8\times 0.48=\Delta K.E.$

K.E.-0= $4.22$

K.E.= $4.22\ J$

1. What do you need to change the momentum of a system?

N76 [4]

1. Momentum (P) is a equal to mass (M) times velocity (V). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (triangleP) over the change in Time (triangleT). And the change in momentum (triangleP) is also equal to the impulse (J)

A 10v battery is connected in series with 2 resistors. R1 is 1 ohm and R2 is 4 ohms. What is the current that goes across R1?

Digiron [165]

Answer:

Current in circuit = 2 amp

Explanation:

Given:

Voltage of battery = 10 V

First Resistance R1 = 1 ohm

Second Resistance R2 = 4 ohm

Resistor connected in series

Find:

Current in circuit

Computation;

Resistor connected in series

So,

Total resistance R = First Resistance R1 + Second Resistance R2

Total resistance R = 1 ohm + 4 ohm

Total resistance R = 5 ohm

Current in circuit = V / R

Current in circuit = 10 / 5

Current in circuit = 2 amp
