The amount of matter contained by an object is called mass.
A. mass
<u>Explanation:</u>
Mass is fundamentally a property of any physical amount and it is additionally the estimation of the resistance from the acceleration when force is applied on an object. The mass equals the quality of the gravitational force on a body.
Mass, in material science, the quantitative proportion of idleness, a crucial property of all matter. The greater the mass of a body, the littler the change created by an applied power. The mass of an object can be portrayed by its capacity to oppose a given power (we once in a while call this a body's inertial mass and subsequently mass is personally connected with the idea of inertia).
This is a straightforward result of Newton's second law where the power F, on a body is equivalent to the mass m, times the speeding up an, it encounters, ie:
F=ma or m=F/a
Mass of an object can not be zero but weight can be zero. The mass and weight of an object are different things.
Answer:
f=896Hz
Explanation:
Given data
Vs(speed of the ambulance)={(104 km/h)*(1000m*(1 h/3600)}=28.9m/s
f(frequency of the ambulance siren)=821 Hz
v(speed of sound)=345 m/s
Vo(speed of the observer)=0 m/s
To find
f(The ambulance is approaching the person)
Solution
From Doppler effect
As the ambulance approaches the we assign a positive sign for speed "vs" of the ambulance
So
Substitute the values from given data
The deceleration of the car is observed as 2 m/s^2.
<h3>What is deceleration?</h3>
The term deceleration has to do with the decrease of velocity with time.
Given that;
v = 65 km/h or 18 m/s
u = 126 km/h to or 35 m/s
t = 8.5 s
a = ?
v = u - at
18 - 35 = -8.5a
a = 18 - 35/-8.5
a = 2 m/s^2
