A toy car has a mass of 1500g. If a 3-N force is applied to the car, what will it's acceleration be?

1 answer:

4 0

F = m * a
F: force = 3N
m: mass = 1500g = 1.5kg
a: acceleration = __ m s⁻²

3 = (1.5) * a
3 / 1.5 = 1.5a / 1.5
a = 3/1.5
a = 2 m s⁻²

Hope this helps! :)

Here is your answer

b) $\huge 1.5× {10}^{11} Hz$

REASON :

We know that

Velocity= Frequency× Wavelength

So,

Frequency= Velocity/wavelength

Here,

V= 3× 10^8 m/s

Wavelength= 2×10^-3 m

Hence,

Frequency= 3×10^8/2×10^-3

= 3/2 × 10^11

= 1.5× 10^11 Hz

A typical mattress has a network of springs that provide support. If you sit on a mattress, the springs compress. A heavier pers

GenaCL600 [577]

Answer:

Explanation:

Spring has a tendency to store energy in them and deform its shape when force is applied on it. Once the applied force is removed it regains its original shape and size.

It is in helical shape and is used in mattress to give structure and support. Spring have elastic nature and follows spring forces, F = k * x

where is the applied force, k is the spring constant and x is the amount of extension.

When a heavier person sits on a mattress, more weight is applied on springs and they form coils, as weight is removed they regains its shape again.
