1) 211m/s
2)240<span>°
3)759,600m or 759.6 km</span>
Answer:
They are both correct.
Explanation:
The density of an object is defined as the ratio of its mass to its volume. This implies that the density of the object is both proportional to the mass and also to the volume of the object. John only mentioned mass which is correct. Linda mentioned the second variable on which density depends which is the volume of the object.
Hence considering the both statements objectively, one can say that they are both correct.
Answer:
option B
−1.92 m/s2
Explanation:
Given in the question,
time took by truck to slow down = 3.56 sec
initial speed of truck = 112 km/h
final speed of truck = 87.4 km/h
1 km/h = 0.277778 m/s
112 = 31.1 m/s
87.4 = 24.28 m/s
Formula use to calculate the acceleration
v - u = at
where v is final speed
u is initial speed
a is acceleration
t is time
plug values in the equation
24.28 - 31.1 = a(3.56)
-6.8 = a(3.56)
a = -6.8 / 3.56
a = -1.9 m/s²
Answer:
The correct option is;
3 times of X
Explanation:
The algebraic properties of a vector are;
Multiplicative identity for real numbers 1
1P = P for each P
Scalar associative property = r(sP) = (rs)P
Scalar distributive property (r + s)P = rP + sP
Vector distributive property r(P + Q) = rP + rQ
Additive inverse of a vector such that a vector P has an inverse -P such that we have;
P + (-P) = 0
Vector associative property (P + Q) + R = P + (Q + R)
Vector commutative property P + Q = Q + P.
