What is the force in N of an object that has a mass of 7 kilograms and acceleration of 6 m/s/s

Physics
1 answer:
Marina86 [1]3 years ago
4 0

Newton's 2nd law of motion:         Force = (mass) x (acceleration)

If you want to move a 7-kg object with an acceleration of 6 m/s²,
then you will need to push it with (7 x 6) = 42 newtons of force.

You don't mean the force of an object.

If a stress of 1.05 × 107 n/m2 is applied to his ligament, how much will it stretch? the young\'s modulus for the acl is 1.10 ×
Ainat [17]

As we know that

Young's\: Modulus = \frac{stress}{strain}

here we know that

Young's Modulus = 1.10 \times 10^8

stress = 1.05 \times 10^7

now by the above formula we will have

1.10 \times 10^8 = \frac{1.05 \times 10^7}{strain}

strain = \frac{1.05 \times 10^7}{1.10 \times 10^8}

strain = 0.095

In a simple electric circuit, a 110-volt electric heater
Readme [11.4K]

Answer: 55 ohms

Explanation:

Given that,

Voltage of heater (v) = 110-volt

Current drawn by heater (I) = 2.0 amperes

resistance of the heater (r) = ?

Since voltage, current and resistance are involved, apply the formula for ohms law.

Voltage = current x resistance

i.e v = ir

where r = v / i

r = 110 volts / 2.0 A

r = 55 ohms

Thus, the resistance of the heater is 55 ohms

what is the energy of a single photon of ultraviolet light with a wavelength of 30.0 nm? 1 nm=10^-9 m
Arada [10]
From the planks equation
E=hv
V= c/ wave length
V= 3×10^8/30×10^-9
=1×10^16
E= hv
6.63×10^-34×1×10^16
= 6.63×10^-18
