An ammeter with a resistance of 5.0 ohm is connected in series with a 3.0V cell and a lamp rated at 300 mA, 3V. Calculate the cu

Alex

Answer:

I = 0.2 A

Explanation:

Lamp is rated at 300 mA

I_lamp = 0.3 A

Voltage is; V = 3V

Thus; Resistance is given by;

R = V/I

R = 3/0.3

R = 10 ohms

Now, since the ammeter of 5 ohms is connected in series with the lamp. Thus equivalent resistance;

R_eq = 10 + 5

R_eq = 15 ohms

Ammeter current will be;

I = V/R_eq

I = 3/15

I = 0.2 A

.a car increases its speed from 10 m/s to 20/s in 2.5. seconds calculate it’s acceleration

Mekhanik [1.2K]

Answer:

$\boxed {\boxed {\sf 4\ m/s^2}}$

Explanation:

Acceleration is the rate of change of an object with respect to time. It is the change in velocity over the time.

$a= \frac{v_f-v_i}{t}$

The car starts at 10 meters per second and increases to 20 meters per second in 2.5 seconds.

$v_f$ = 20 m/s
$v_i$ = 10 m/s
t= 2.5 s

Substitute the values into the formula.

$a= \frac{ 20 \ m/s - 10 \ m/s}{2.5 \ s }$

Solve the numerator.

$a= \frac{10 \ m/s}{2.5 \ s}$

Divide.

$a= 4 \ m/s/s$

$a= 4\ m/s^2$

The acceleration of the car is <u>4 meters per second squared.</u>
