kompoz [17]

Answer:

0.5 m/s².

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 0 m/s

Final velocity (v) = 10 m/s

Time (t) = 20 s

Acceleration (a) =?

Acceleration can simply be defined as the rate of change of velocity with time. Mathematically, it is expressed as:

a = (v – u) / t

Where:

a is the acceleration.

v is the final velocity.

u is the initial velocity.

t is the time.

With the above formula, we can obtain the acceleration of the car as follow:

Initial velocity (u) = 0 m/s

Final velocity (v) = 10 m/s

Time (t) = 20 s

Acceleration (a) =?

a = (v – u) / t

a = (10 – 0) / 20

a = 10/20

a = 0.5 m/s²

Therefore, the acceleration of the car is 0.5 m/s².

Tensile stress is: A. the strain per unit length. B. the ratio of elastic modulus to strain. C. the ratio of the change in lengt
victus00 [196]

Answer:

D. the same as force. the applied force per cross-sectional area.

Explanation:

Tensile stress of a material is defined as the ratio of the applied force on the material to its cross sectional area. this is expressed mathematically as;

Tensile stress = Force/cross sectional area

Tensile stress = F/A

Force is measured in newton while cross sectional area is measured in m

Hence the unit of Tensile stress is N/m²

What is the velocity of a worm moving 1 meter in 2 hours to the East?
malfutka [58]

Answer:

Velocity = 0.0001389 m/s

Explanation:

Given that the

Distance covered = 1 metre

Time taken = 2 hours

Convert the hour to second

1 hour = 60 × 60 = 3600

2 hours = 2 × 3600 = 7200

What is the velocity of a worm moving 1 meter in 2 hours to the East?

Velocity can be referred as speed.

Velocity = distance/ time

Velocity = 1/7200

Velocity = 0.0001389 m/s

Students in an introductory physics lab are producing a region of uniform electric field by applying a voltage to two 20-cm-diam
earnstyle [38]

Answer:

69000 V

Explanation:

E = Electric field = 3\times 10^6\ V/m

d = Distance between plates = 2.3 cm

When we multiply the electric field strength and the distance between the plates of a capacitor we get the maximum voltage.

Maximum voltage is given by

V_m=Ed\\\Rightarrow V_m=3\times 10^6\times 2.3\times 10^{-2}\\\Rightarrow V_m=69000\ V

The highest voltage the students can use is 69000 V
